upon running pip install trains in my virtual env

I am getting

I know that I am not supposed to run under sudo when using a venv, so I don't really understand the problem

running for example pip install pandas does work.

Python 3.8

How to install trains?


EDIT:

running pip install trains --user or pip install --user trains gives

ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

The problem was a permissions problem for the venv. Another problem was trains required some packages that were not yet available with wheels on Python3.8, so I had to downgrade Python to 3.7

That venv was created using Pycharm, and for some reason it was created with low permissions.

There was probably a way to elevate its permissions, but instead I just deleted it and created another one using command line by

python -m virtualenv --python=/usr/bin/python3.7 venv

And now pip install trains worked.

Very annoying.

You have two options:

  1. Create a virtual environment and install your packages inside it (preferred)

  2. Install your packages inside your user home directory by passing --user flag

    pip install --user

I had the same error with installing matplotlib in Ubuntu 18.

Running these lines worked for me:

sudo apt-get install python3-dev
apt-get install build-essential

As found on setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
