OS: Raspbian 10; Python version: 3.8; Pip Version: 20.2.2

I have tried all solutions including the links in this post and still not able to find the solution for a raspbian environment. I am trying to perform pip3 install --no-cache-dir pytest and it gives be the error above. Are there any specific solutions to raspbian or linux environment?

Below is the pip install --no-cache-dir pytest -vvv output. I have highlighted the error (located in the middle) below.

Please add the complete log of pip3 install --no-cache-dir pytest -vvv to the question. – hoefling
@hoefling please see output above. Thank you! – jsibs
Try running pip3 install pytest --extra-index-url=https://pypi.org/simple. Does it install pytest now? If yes, it looks like you have piwheels set as exclusive index in your ~/.config/pip/pip.conf (Raspbian always has one). Check that for a setting index_url = https://piwheels.org/simple and change index_url to extra_index_url. If not, you may have some predefined PIP_* env vars, e.g. PIP_INDEX_URL etc. Check that via env | grep -i pip_. – hoefling
WOW. That worked! I've been working on this all day. Thank you so much. Mind posting it as an answer? Thank you @hoefling ! – jsibs
@hoefling https://piwheels.org/simple was already assigned to extra-index-url located at /etc/pip.conf and nothing came out when I ran env | grep -i pip_ – jsibs

Based on the log you provided, it looks like pip3 install only checks https://piwheels.org when looking for dist files. This indicates that https://piwheels.org is set as the exclusive index in the pip's config:

$ cat ~/.config/pip/pip.conf
[global]
index_url = https://piwheels.org/simple

Or check that via pip3 config:

$ pip3 config list 
global.index-url='https://piwheels.org/simple'

This will ignore https://pypi.org completely when looking for dists which is not you want, since piwheels only contains a small part of packages that require special tweaks to be built on ARM. To fix that, change index_url to extra_index_url in the config:

$ cat ~/.config/pip/pip.conf
[global]
extra_index_url = https://piwheels.org/simple

Now https://pypi.org will be queried first; if a package is not found, pip will query https://piwheels.org as a fallback.

Edit

Looks like your setup is somewhat different from what I'd usually expect. As a temporary workaround, you can create the ~/.config/pip/pip.conf with the following contents:

[global]
index_url = https://pypi.org/simple
extra_index_url = https://piwheels.org/simple

However, this only heals the symptoms, not the root issue. I will check that on my Raspberry Pi's tomorrow and add another edit with a proper solution.
