How to recover a missing venv in PyCharm?

If the venv (virtual environment) disappears in PyCharm, you can try to recover it by following these steps:

1. Make sure the virtual environment directory still exists. Check if there is a folder named “venv” in the project’s root directory.
2. If the virtual environment directory does not exist, you can try recreating the virtual environment.
3. Select “File” from the top menu of PyCharm, then choose “Settings”.
4. Choose “Project: [project name]” from the pop-up window and select “Python Interpreter”.
5. Click on the gear icon on the right side of the Python Interpreter list, then choose “Add”.
6. Select “Virtualenv Environment” in the popup window, then click “OK”.
7. Select “New environment” in the next window, and then click “OK”.
8. Wait for a while, PyCharm will recreate the virtual environment.
9. If the virtual environment directory is still present but PyCharm is not recognizing it correctly, you can try reconfiguring the Python interpreter.
10. Select “File” from the top menu in PyCharm and then choose “Settings”.
11. Select “Python Interpreter” in the pop-up window under “Project: [项目名]”.
12. Click on the gear icon on the right side of the Python Interpreter list and choose “Show All”.
13. Choose the correct Python interpreter in the upcoming window, then click “OK”.
14. Please wait for a while, PyCharm will be reconfiguring the Python interpreter.

If none of the above methods work to restore the venv, consider deleting the virtual environment of the project and then creating a new one.
