I'm trying to install glpk using pip on a virtual enviroment but it keeps giving this error regarding the wheels for pip installing "ERROR: Could not build wheels for glpk which use PEP 517 and cannot be installed directly":
$ pip install glpk

I have glpk installed:
$ glpsol --version
GLPSOL: GLPK LP/MIP Solver, v4.65
And the troubleshooting of glpk manual give those output
$ find -P /usr -name "*glpk.*" \( -type f -o -type l \) -exec file '{}' \; 2>/dev/null

I'm using a virtualenviroment
$ printenv | grep PATH
WINDOWPATH=2
PATH=/home/yuri/tech/data-science-beeftrader/venv/bin:/home/yuri/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
And this is my pip version
$ pip --version
pip version 20.1.1
p.s: I've already tried some of the solutions found online such as --no-binary and --no-use-pep517
回答1:
After triyng some different solutions to my problem, I was able to solve it by installing this three packages:
sudo apt install libglpk-dev python3.8-dev libgmp3-dev
And after that running the same command:
pip install glpk
