Failed to create a virtual environment

Hi! Whenever I create a new project, or try to create a run configuration, an error occurs saying: "Failed to create a virtual environment"

(A picture of the error)


(My settings and stuff for the project)


Hi, `idea.log` in "Help | Show Long in ..." should reveal the problem. Try to reproduce the problem and send the log to Feel free to inspect the file yourself.

P.S.: We will improve the error messaging.


Create a virtual environment
Ensure that you have downloaded and installed Python on your computer.

Do one of the following:

Click the Python Interpreter selector and choose Add Interpreter.

Press Ctrl+Alt+S to open the project Settings/Preferences and go to Project <project name> | Python Interpreter. Click Python interpreter and select Add.

In the left-hand pane of the Add Python Interpreter dialog, select Virtualenv Environment. The following actions depend on whether the virtual environment existed before.


I have the above problem on windows. How do I solve it?


Aiden Song There could be many root causes for this issue. Could you please send the logs as instructed by Pavel above?


I arrived here from google with the same issue.  I can't create or use ANY env or venv from existing or new projects within Pycharm after a fresh install on a VM.

In my cause the "cause" is network UNC paths, AGAIN.  This used to be fixed.  Seems Windows 10 in a VM does not handle network file transactions very well.  Lot of errors like "not a directory", when in fact it IS a directory and it is perfectly valid.  It seems as though the directory gets created, but there is a concurrency issue with the next thread trying to read/write to the directory and it seemingly hasn't actually been created "yet".  Suggesting an async setting in the network or disk settings.


NotADirectoryError: [WinError 267] The directory name is invalid: '\\\\\\paul\\devel\\home_auto\\home_heating\\venv\\Lib\\site-packages'

However, if I copy and paste that line into explorer.... it opens fine.

I do not, in my case, think this is a JetBrains issues as Eclipse does similar things on this VM when anything is put on network drives.  I need to check network synchronisation settings.


Now I have this:


IsADirectoryError: [Errno 21] Is a directory: '\\\\\\paul\\devel\\home_auto\\home_heating\\venv\\Lib\\site-packages\\setuptools\\command\\'

No... it's really not.

<insert frustrated rant> about Windows networking being junk.  Network drives SHOULD BE 100% TRANSPARENT!


I suffered from similar problem.

In my case, console encoding was a problem. Changing console encoding from x-windows-949 to utf-8 fixed the problem.

Ensure that Python is installed on your system and is accessible from the command line. You can check the Python version by running:

Upgrade pip: It's a good practice to ensure that your pip Siding Replacement Estimates  is up-to-date. Run the following command:

bashCopy code

python --version
