使用不正确的 Python 可执行文件激活虚拟环境

Question

I am working on a project through PyCharm. When I started the project, the project interpreter was a newly created virtualenv located in my project folder at /path/to/project_folder/venv and using base interpreter /usr/bin/python3.6 .

When working in PyCharm, the Python Console seems to be using the right venv/Python executable etc. Running os.system("which python") returns /usr/bin/python .

Next, I activate this venv through my terminal (on Ubuntu 18.04) using the command source /path/to/project_folder/venv/bin/activate which works fine and shows me that it is activated with a (venv) . However, if I run which python , it returns /home/user/anaconda3/bin/python .

Why is this occurring? How can I access the same Python interpreter from the PyCharm console through my Ubuntu terminal?

Answer 1

Same happened to me in a specific project.

Symptoms:

• No executable taken from the venv; ie:
• which python3 from bash is not taken from venv
• Python packages are not working from venv

Cause:

• You renamed your project folder
• Virtual environment PATH keeps old path to venv
• It fails silently

Solutions:

1. Create a new venv and reinstall requirements, OR
2. Rename folder to its old name

Change PATH is not the solution. venv script creates some other routes in various files.

Note: Tested with python3 -m venv venv
