无法导入Arch Linux上与pacman一起安装的python软件包

Question

Whenever I try to import a python package that I installed via pacman, I get the error

ModuleNotFoundError: No module named [packageName]

In the past, I have just got around this issue by installing the packages that I need via pip, which works fine. However, in this case, that is not an option

Here's some stuff which might be useful to know - I'm not sure which parts of this information are relevant, but anyway:

• Running python tells me that my version is Python 3.6.4 |Anaconda, Inc.
• Output of which python is /home/username/miniconda3/bin/python
• I have the line export PATH="/home/username/miniconda3/bin:$PATH" in my ~/.bashrc
• Running import sys , print(sys.path) gives ['', '/home/username/miniconda3/bin', '/home/username/miniconda3/lib/python36.zip', '/home/username/miniconda3/lib/python3.6', '/home/username/miniconda3/lib/python3.6/lib-dynload', '/home/username/miniconda3/lib/python3.6/site-packages', '/home/username/miniconda3/lib/python3.6/site-packages/Mako-1.0.7-py3.6.egg', '/home/username/miniconda3/lib/python3.6/site-packages/IPython/extensions', '/home/username/.ipython']

(In case you hadn't guessed, I'm very new to Arch, and not particularly experienced with Python, so I would be grateful for any assistance)

Answer 1

Anaconda's Python interpreter is isolated from the system. If you install anything system-wide, your Anaconda's Python won't be able to find it.

If you want/need to use Anaconda you have two options:

• use conda
• use the pip that comes with Anaconda (which very likely is the version that you are using)

Otherwise don't use Anaconda: remove /home/username/miniconda3/bin/python from your PATH and use the system python (should be something like /usr/bin/python ). The system python knows where to look for packages installed with your system package manager, eg packman )
