Arch Linux on Termux:

$ pylint --version
pylint 2.3.1
astroid 2.2.5
Python 3.8.0 (default, Nov 14 2019, 15:41:40)
[GCC 8.3.0]

Termux:
$ pylint --version
pylint 2.3.1
astroid 2.2.5
Python 3.8.0 (default, Nov 20 2019, 20:44:46)
[Clang 8.0.7 (https://android.googlesource.com/toolchain/clang b55f2d4ebfd35bf6

import random
throws an error with code E0001 when used in python source.

(Should this be a pylint issue or should I post it on the Github projects for Termux and/or ArchLinux for Termux?)

Can you post the exact file that triggers this exception as well as the output? There must be something amiss especially since random is a stdlib package and pylint should find that without issues.

Updated with error.
Similar error running it on ArchLinux for Termux.

On installing prospector via pip , I was able to reproduce the error importing the modules once more.

I receive the following error when installing pylint after installing prospector:

ERROR: prospector 1.1.7 has requirement astroid==2.2.5, but you'll have astroid 2.3.3 which is incompatible.
ERROR: prospector 1.1.7 has requirement pylint==2.3.1, but you'll have pylint 2.4.4 which is incompatible.

I then have DistributionNotFound errors while running prospector.

Do I need to open a separate bug on Prospector or will you do the needful?

Sorry I'm not entirely sure how to reproduce this error, so feel free to report a bug on Propsector side as well.

pip install prospector==1.2.0.dev3
is the solution for now. Closing this issue.
