#Python #venv
In my older virtualenv video, I got a ton of requests to show how to use virtual environments on Windows. I hope this helps!
Hey Corey, thank you as always, i was trying to debug a Python for loop and was not sure if you talk about it anywhere. Also realized that sublime text 3 does not actually feature a python debugger, would appreciate your thoughts on this.
Thank you for all your videos. You should do one someday for pipenv!
And multiprocessing/multithreading
And sockets!
@@guipa I already have one for Pipenv. You can find that here: ua-cam.com/video/zDYL22QNiWk/v-deo.html

The second hero after Corey Schafer :)
Thank you sir.
great job mate, thanks!
Is there any way to find out my existing virtual env?
Corey...You are the Guru of python world..thanks a lot for sharing your knowledge as always!
in short
(i am assuming you have activated virtual environment)
type: pip freeze
(you will see all requirements)
copy all to requirements.txt (16:40 observe copying process carefully)
//(make sure requirements.txt is in project folder)
type: deactivate
(venv will be deactivated)
type: pip install -r .
equirements.txt
(all requirements will be installed)
type:.\venv\Scripts\Activate.ps1
(activating environment)
This has been so helpful! My class focused mostly on programming, and so we didn't really understand what we were doing during setup, but your videos make it very clear and easy! Thank you!
Thank you for this tutorial! I couldn't figure out how to use VENV on my own, even though I read a book called " Test Driven Development" because the author explained how to use VENV on mac. Corey, you're the man!
Great tutorial! I am a hobbyist programmer, not an expert. I have been learning my self and this really helped.
This video saved me in setting up venv in windows, still relevant in 2021
This is just perfect. I had been looking to understand venv for quite sometime now, and this clears it all. Great job!!!
This is exactly what I needed just now for my project which is rapidly growing in complexity. Thanks Corey!
This is a simple and straight to the point tutorial. Well done man.
You've just gotten a subscriber.
Me too that was one of the best tutorials for real
This is the best venv tutorial that I've ever seen. Its bookmarked in my browser for over 1.5 years now. I get back to it whenever I miss something. Thanks man (y)
Thanks @Corey Schafer. trying to follow some Django tutorial on UA-cam but just couldn't activate the virtual env, windows would accept the CMD but won't activate the venv :
Setup: win 10, gitbash, python 3.7
Create the venv: python -m venv my_dir
Activate the venv: source my_dir/Scripts/activate
Stackoverflow to the rescue. Love your work btw thanks from the rest of us.
I really needed this video.
Thanks Corey!!
This is the best video I've seen this year so far!!! I might be exaggerating but you sir have helped me solve a problem I was working on for the last 20+ hrs!
i was totally confuse and frustrated just before completing the 17 minutes of this video
honestly i feel really relief now..
you got a new fan now man.....
thank you...
Thanks Corey for creating this, I think every UA-cam turorial uses Mac, and I could not find a decent source for learning Virtual Environments...
Good video, cleared a lot up. The programming is easier than the setup.
This was great. I was thinking of questions as the video moved along and then you ended up answering them all. Great work Corey.
He does that doesn't he. One of the most clear videos on venv.
jesus you don't know how much this helped me. All tutorials I've watched were done on Mac haha
Super..
Even after 4 years, it is still a valid a video 😍
This video is a simplified as a sip on a cup of coffee thank you so much Corey
Thank you Corey, I almost gave up trying to work with venv, until i saw this brilliant post...
Yet another video from maestro Schafer that makes difficult subject looks pretty easy.
Respect!
Thank you so much! I’ve searched and read and tried everything on the net on how to set up venv but this is the only one that worked.
You're right, is is simple and doesn't have the bells and whistles of pipenv. The one thing I really prefer in pipenv is your pipfile is update automatically. Here, you would have to remember to add something to your requirements.txt after you install it.
Thank you so much for resolving the issue. other videos on UA-cam wasted my time.
The single most important Python tutorial since Python's existence. Virtual environments are the most effective anti-hair loss treatment ever invented :)
Many thanks for this tutorial. You have saved me from what I spent a whole weekend trying to figure out.
I want to confirm that I understand it correctly.
So the venv module here, is used to create... a virtual environment.
it's like a copy of python, but one that I can mess around with and don't have to worry about.
once I'm done with it or don't need it anymore, I can simply delete it like deleting a normal folder.
whatever I do in the virual environment, doesn't affect the main python installation (/AppData/Local/.../Python).
This guy is a real instructor. Great work a lot of effort there thank you
Thx Corey! This video is still helping me out in 2022
This is a very good video to learn venv module in short time. I appreciate your work.
This is very well explained and easy to follow. Thanks for the tutorial!
Thank you Corey for this excellent video on virtual environments. I needed it. You do not assume anything as known and this is very good, especially for beginners. For me, the best explanation on this topic I found!
Corey, I watched lot of videos about the environment and virtual environment but could not understand. Your explanations technique is the best. Thanks.
To create the enviroment on python 3.8 the command is: py -m venv
This guy is the GOAT, simple and easy tutorials! This helps alot!
Nice video. Conda has been acting weird with pip packages so I've ditched anaconda and gone this way. Minor note, you can leave off the .bat when activating
You are the best I have been like 2hour trying to figure it out , and with you it took like 1min
Super helpful. Clear, concise, to the point. Thx much, m8.
You are talking very fast, but you covered everything important to know. Many Thanks for that
you are unique, keep it up !!!!!!!!!!!!!!!!!!!!!!!!!!
@ 3:34 my issue was solved thanks for the content!
Pretty much what the rest of the comments say - great video and thanks once again!
Thank you very much for this video :) It is very helpful and I learnt a lot!
Excellent explanation
You are the best instructor!
you are awesome i don't have words to describe how helpful this video was thanks alooot man
Your videos are the best. Thanks for sharing your knowledge.
Most simplest explanation there can ever be! 100000%
Thank you so much, love how simple and clear this tutorial is! :)
This video really helps me a lot. Hope you'll make more videos like that.
Thank you so much. In 2021 this video is really good, but i had changed the second command to "python3 -m venv project_env". Just add the 3 in python.
Just to add something to this great tutorial. we can dump the result of "pip freeze" into "requirements.txt" file by doing
pip freeze > requirements.txt
removing the need to copy the pip freeze results manually.
I think he was saying this caused his command prompt to change colour hence why he didn't do it
Very good one! Thank buddy. I like your videos. Your attitude and way of passing the stuff to your viewers is just excellent.
very well explained...thanks...
for PowerShell:
activate command: your_venv_dir/Scripts/Activate.ps
to deactivate command you should just enter in PowerShell: exit
Thank you, that was really informative! Clears up questions.
i keep getting modulenotfounderror: after setting up VENV and activating, i am trying to use this for my python interpreter in visual studio code and none of installs are found. it looks active but even right after installing i do see more module in pip list than expected. any guidance on a step i am missing.
Hey there, that was a really helpful video! :)
I have just a few questions:
1. How do I open this on VS code then? If I create a new file in VS code under the project folder where my venv is (so on the same level as the venv) and open the Command Palette and search Python: Search Interpreter and choose the venv does it apply to my file? Or also to all other files?
2. If your script file is outside the venv directory then how will the script access venv packages?
3. The pip list is not working... Do I have to install something first?
I hope you see this and can help me get along. Thanks in advance! :D
these are great questions, waiting for the answer too
Great videos Corey. You are the go to when I am looking to understand something python. Thanks for helping the community!
Thank you Corey, you actually explained away all the questions
a noob like me came with. Things I just didn't understand and most videos
skip, I guess cuz its obvious to the creator. Very helpful tutorial 🙏 thank u
Thank you very much it was very useful
Never found a more fitting video to my problem, thanks a lot!!
Export pip list:
pip freeze > requirements.txt
Import pip list:
pip install -r "requirements.txt path"
Create Env with pip packages:
python -m venv "projectName" --system-site-pakages
Thank you for this, you are the foundation of whatever i do or develop related to python
This is helpful Corey, comprehensive and good phase!
Sir, you're just best.
If anyone wants to automate the creation of requirements.txt file then just type in this:
*pip3 freeze > requirements.txt*
It will automatically save that.
pip freeze > requirments.txt is how you copy your requirements in .txt file
If I could like the video 10x I would, thanks bro
thank you sir your video clear my lost of doubts
My man...I've been struggling with this. Great video. Thank you so much.
This video was great for me, I'm just learing python for the first time and as a windows user it was easy to follow the steps, congratulations. It would be great if you are able to add the english subtitles in the video because as me that I'm not an english person many other people could watch the video easer reading the subtitles
Thank you Corey. All this virtual environment stuff was really confusing regarding how many of them there are. I'm going to stick with the baked in one, venv.
Thank you for sharing! saves a ton of time, trying to search for solutions on your own
Very helpful and you make it very intuitive, thank you!
This is the best video on the subject of python virtual environment! Thank You .
If you guys can't figure out why your venv doesn't show up when you activate, consider checking if you are running cmd or power shell. The command for powershell: PS C:\> \Scripts\Activate.ps1
Corey, I tried running venv but I got this error:
Error: Command '['C:\\Users\\Fillipe Madureira\\Desktop\\project_env\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 101.
Can't find what it means... Any idea?
Thanks for the help and all the tutorials, man. They have been incredibly useful to a newcomer.
Very helpful. Thank you!
This was so helpful and concise. Thank you very much from a Python (heck, programming in general) noob!
Awesome and Easily understandable explaination.
It is possible to just add the requirements.txt by using the pip freeze > requirements.txt command without creating the file ourselves
Great video
Loved the solution finally my problem is solved.. bless you man.
Great video. Really good explanation.
Thanks a lot for sharing this informative information beautifully
Espectacular la explicacion.... Buenisimo... Gracias.
Thanks a lot for the info you gave us. I was searching through the internet on how to activate a venv. Nothing was useful for me.
For people struggling to activate on windows (10) with gitbash/cmdr/comemu etc try,
$ source venv/Scripts/activate
Thanks Corey Schafer, it was a very helpful tutorial!
Best video to understand Virtual Environments Corey the messiah ! UwU
Lol. I like Google's algorithms. Today I was looking for "how to launch virtual environment" to use Django and now this is in my recommendations. (Sorry for my bad English and hello from Russia)
I know right.
They didn't used to have all this info for coding.
It's the one thing Google actually gets right.
Which shows they know how to recommend content. (This is significant because normally they suppress content)
(They normally suppress any good non coding related content like debates bloodsports, shitposting channels etc etc,
But coding info they've been very good at)
Awesome Man . You are awesome Corey . Thanks a ton . I love the way you make things simpler .
Great job. I found this very helpful.
Thank you! That was the best explanation I encountered on UA-cam!
i wish i could give more than one likes to this dude.
noob query : If your script file is outside the venv directory then how will the script access venv packages ??
Yeah thats what i thought too
excellent explanation...as usual... thanks a lot
