I'm using PyCharm for a project, and I've been having a problem I can't understand. In the "terminal" (in PyCharm), I activate the virtualenv I want, which has Python and all my other packages. The project works, which means the packages are being found, because otherwise it wouldn't work. But the thing is, neither python nor pip are recognized in the PyCharm terminal. This happens whether the virtualenv is activated or deactivated, so I don't think that's the issue.
I get the "python is not a recognized internal or external command" message, but if I do it in the file system, for instance, I can use python, pip, and everything else just fine, so I think it might be a configuration of my PyCharm, most likely, but I don't even know where to look, I don't see anything in the settings that I find odd. Any help could save me a lot of time I've been stuck with this. I'm on Windows 10, by the way.
The environment variable 'PATH' is 'C:\Users\Iván\AppData\Local\Programs\Python\Python36', and python is recognized anywhere but within the PyCharm terminal.
If you are using windows.
You have to add paths to python & pip in environment variables. If you have no previous experience doing so. I would ask to use this link https://www.youtube.com/watch?v=DrhkbjDAUV0.
If I am getting your problem wrong sorry.

It's been a while since I posted anything here, and now my problems have become more advanced. For reference, I'm running on Win10.
I'm trying to use the Django framework. Python's been installed on my computer forever; it's the latest version, and it's installed on environment variables/added to system paths. I think those are enabled by default, but I did make sure that they were checked when I reinstalled it.
pip's been updated too. Django installed successfully. I managed to get all the way to installing my new project with django-admin startproject PROJECTNAME, but when I try to run python3 manage.py runserver, I'm getting this error:
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
This "Python was not found" error is the main problem that I'm trying to figure out. Nothing I do as a fix seems to get rid of it.
...Interesting. If I type in python --version, I get a response (Python 3.11.0). Here's what I get if I do pip freeze:
asgiref==3.6.0
Django==4.1.6
sqlparse==0.4.3
tzdata==2022.7
Python IDLE runs fine; all .py files run fine. Alright. So, with that in mind and in accordance to a lot of popular advice I've seen floating around, I added the Path to my Environment Variables. For space-saving reasons, my Python is installed on my D drive rather than C. I've made sure that there weren't any leftover Python files that conflicted.
I've uninstalled and reinstalled, double checked my installations, and Django is in D:\ProgramData\Python311\Scripts with pip and everything else I need. I did also disable the shortcut from Settings > Manage App Execution Aliases, but when I did that, I got this error:
python3 : The term 'python3' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Based on some other things I've seen, I've also tried:
python manage.py runserver
python3 ./manage.py runserver
I ended up having to enable the options again just to use Python correctly. And I have been closing and reopening the command line whenever I make changes. Though it updates automatically to fit what I've been doing, I wanted to make sure I didn't overlook any possibility.
I even uninstalled Django for a third time, installed the virtual environment (which I realised I skipped), and did it all again. And then, after a long series of figuring out how to activate the virtual environment and enabling scripts to run, I'm finally in (venv) D:\PROJECTNAME, and I tried... to run it again.
I'm still getting the Python not found error. orz
I've been at it for two hours or so, and I feel like I'm running into a dead end. I think I've finally met my match here.
This is my first time using frameworks like this, and it's been a while since I've installed anything through command line on Windows. I'm not very great at this, so I know that I'm making some amateurish mistakes somewhere. Please let me know if I'm doing anything wrong or missed something obvious.
Please.... I just want to use Django....
Thanks in advance!
This question really is not proper for a PowerShell Q&A, but let see if the below helps.
If you are trying to run django from PS, then:
pip install django
django-admin startproject YourProjectNamehere
lastly, hit your dev server
HTTP://YourDevServerName:YourDevServerPortNumber
Also, be sure that you've activated your virtual environment, never assume it is until you test it. Of course, be sure to change directly to the root of your project.
Again, if you are using python, directly, then, it's more prudent to stay in your pristine python shell vs executing from a PowerShell consoler/terminal, thus eliminating any PowerShell particulars.
first download manually python on your computer , therefore install django from official website , www.python.org/downloads/, https://www.djangoproject.com/download/,
if you're on linux, pip install Django==4.1.6
after installing that use ,
django-admin
I can enter into my terminal (wsl) python3 filename.py and the code executes in the terminal just fine. But when I hit the play button (Run Python File) I get errors
C:/Users/user1/AppData/Local/Programs/Python/Python311/python.exe "c:/Online Learning/Coder Academy/Python/Lesson-3/test.py"
zsh: no such file or directory: C:/Users/user1/AppData/Local/Programs/Python/Python311/python.exe
I don't see why if the code is executing fine from the terminal by typing in the command. Why can't I hit the play button without error?
I've tried a lot of things including using extension Code-Runner. Uninstalling and re-installing various versions of python. I've tried pyenv, defining various different interpreter paths.
I'm thinking it's not the set up of my python in wsl it's something to do with a setting in VSCode.
I'm not totally sure, but it seems to be coughing up that "python.exe" doesn't exist. What I remember doing is checking if "py.exe" works and see if the problem is resolved. If so, go to where VSCode says Python is and copy py.exe to your desktop, rename it to python.exe and paste it back to the folder where py.exe was. It may not be good practice, but was my workaround. I guess the best thing to do is just to reinstall Python.
I would agree with the setting in vscode.
hitting cntrl+shift+p, type python, hit 'select' interpreter will let you pinpoint exactly where vscode thinks the interpreter is.
For many reasons I would strongly recommend using a virtual env. For the purposes of this discussion, you know that you'll be creating a folder that has a version of python in it that you can select.
Best of luck. these issues can be very frustrating
I understand that the fact that having to type "python3" or "pip3" instead of "python" and "pip" respectively is an annoyance at worst, however it makes me paranoid that other things that I install to my vscode will also have to be run differently. Every other programmer that I watch doesn't have to do so.
zsh: command not found: python
Could it possibly be an issue with my pathing of my downloads?
This, of course, has nothing to do with VSCode and everything to do with the install of Python on your machine. However, it is strange to not have the Python available with just python at the shell.
In any case, one simple way to solve this issue is to open (or create) ~/.zshrc and add the following line:
alias python="python3"
This is a common thing in particular for macOS users, where python often points to the pre-installed Python2.7.
Restarting terminal/VSCode after making this change should fix your issue.
I'm trying to add my Python interpreter to PyCharm but whenever I navigate to python.exe and click Ok it says Invalid Python interpeter name 'python.exe'! (the spelling mistake for interpeter is how it's spelled in the dialog that appears)
I installed Python through the Microsoft app store. The interpreter is located at ~\AppData\Local\Microsoft\WindowsApps\python.exe. This is the path I navigate to when selecting the interpreter in PyCharm. There are also python3.exe and python3.7.exe but those don't work either. I can run python from the command line and it behaves as expected.
I got the same error message when I imported a project of an existing virtual environment to pyCharm. Though the name and path of the exe was correct, pyCharm did not accept it.
My solution was to remove the Interpreter in pyCharm and to add it again. Then the Error was gone. Perhaps that can help someone ...
The EAP (Early Access Program) build Pavel suggests did not work for me. I hope this gets sorted out in PY-33406 as Pavel suggests.
In the responses for that issue, the thing that worked for me is included. I created a virtual environment using venv and was able to use that python interpreter. As it says on that page...
Open the windows prompt
Go to the project root: cd X:\path\to\project
Type python -m venv venv
Chose "existing interpreter" instead of
creating a new venv using Pycharm and pick the Python binary from the
virtualenv you created in the previous step
Hope that helps, happy to update this to add more detail if not.
Remove the interpreter (by using minus sign) and add it again!
In case anyone else is still facing this issue, reinstalling PyCharm did the trick for me.
If you're adding an already existing virtual environment, it may sound dumb but check that the python executable does exist. If it's a symlink, it should point to a valid location in your system.
In my case, I had overwritten the already existing python executable with a new python executable created by clicking the "new" option in the virtual environment creation by mistake, and the result was an incomplete virtual environment setup in which the python executable was a symlink to a non-existing python executable. Recreating the virtual environment from scratch and using it as an "existing" virtual environment solved the issue.
I know these are basic checks, but hopefully this helps someone out there who rushed for an answer.
Try PyCharm 2019.2 EAP build. The problem should be fixed: https://youtrack.jetbrains.com/issue/PY-33406 (or better use Python from python.org).
I reported the typo to PyCharm's bug tracker, thanks https://youtrack.jetbrains.com/issue/PY-36686
I installed PyCharm 2.7 under Windows 8.1. It works fine, but every time I run a program, I get the following warning:
WARNING:root:No virtualenv active
Why does it happen and how can I fix it?
Program you run needs a virtual environment to run. This is a nice python feature that allows you to isolate a python program within the scope of the specific python set of libraries it may need. If you do not run more than one Python program you may not be really worried about it. However, it you do, I would recommend to ready about virtualenv first.
ps. Also, it might be just a debug log for developers to make sure they switched virtual env.
