QUESTION

Docker: Cannot install specific pip packages

Asked 2021-Oct-12 at 10:16

I want to install specific packages in a docker container. For most of them, the pip installation works fine. However, it seems like some of the versions of the packages cannot be found.

Here's the requirements.txt file from which I'm installing the packages. It was obtained from pip freeze done in PyCharm from Windows.

Currently, I am trying to install them in Docker working on Ubuntu 20.04.

ANSWER

Try to use some other version of ipython.

Replace the python version in your requirements.txt with:

ipython==7.24.1

However, it doesn't have anything to do with docker configuration i.e. --network=host
