Python找不到安装的模块

Question

EDIT: Thanks to michcio1234, the problem is solved in the answer below.

ORIGINAL QUESTION: I created a python package (called precom ), installed via pip install . into a defined conda environment (also called precom ) and tried to load the package.

When loading the installed package in ipython , it is not found. However, when I do conda list , the package is listed (see output below).

This is really strange!

I googled, checked stack overflow, re-coded, re-installed but it never worked. Does anyone have an idea what I am missing?

Answer 1

You don't have ipython installed in your environment, so what you are running is not actually in your precom venv.

Try pip install ipython or conda install ipython , or just run python and then try to import your package.
