ModuleNotFoundError: No module named 'moviepy' although it is installed

Question

I'm working with Python 3.10.11 on Windows 11 using freshly created venv. I installed moviepy using pip, now if I do

(venv) PS D:\Projects\bot for circles\Telegram-Video-Circle-Bot> pip list

I get

------------------- ---------

tqdm                4.66.1
urllib3             2.0.7

So moviepy is in the list. But when I try to import it, it just not working:

(venv) PS D:\Projects\bot for circles\Telegram-Video-Circle-Bot> python
Python 3.10.11 (tags/v3.10.11:7d4cc5a, Apr  5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import moviepy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'moviepy'
>>>

What can I do to fix it?

I worked without using venv, when I got that error first time, now I switched to venv and created new enviroment, then installed all packages that I needed. It is error that occurs with moviepy specifically, for example, numpy works perfectly:

(venv) PS D:\Projects\bot for circles\Telegram-Video-Circle-Bot> python
Python 3.10.11 (tags/v3.10.11:7d4cc5a, Apr  5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> np.arange(0, 10, 11)
array([0])

Answer 1

I think your PATH is declared in the wrong way. Your path will have pattern like /path/to/A/bin:/path/to/B/bin:/path/to/your/venv/bin

So the python command will exist in also your path/to/A and your venv, but it come from /path/to/A, then the OS will get the python executed file in /path/to/A/bin instead of /path/to/your/venv/bin - which contains the python version that included moviepy.

Verify my idea by using where python vs where pip command

There is 2 way to fix it:

• use python -m pip install moviepy, then use python main.py as usual (recommend for newbie)
• Fix the PATH and move your venv path to the head of PATH variables

Good luck
