Module not found with virtual environment

Question

I can run my app from the console that there is in pyCharm but If I try to run my app from a shell my app doesn't find "pymysql" module.

The module is installed in my project in a virtual environment. You can see in the next image how is installed this module.

And If try to run my app from the shell I've got this error:

I'm using python3.

What am I doing wrong? Is there any easy way to access to the module?

Answer 1

There are several ways:

1. activate virtual env: source venv/bin/activate .
2. directly use specific python: venv/bin/python main.py
3. Surely you can temporarily add venv/bin to your PATH , that's almost the same as the first option: export PATH=full/path/to/bin:$PATH

Generally I recommend the first option. But sometimes you may want to use the second one. For example, you want to use this python in a crontab script.
