Experiencing gcc 5 failure running poetry install on Ubuntu 20.04

Multiple error: command 'gcc-5' failed: No such file or directory..

gcc version: 9.3
poetry version: 1.1.4
python: 3.9.1
Ubuntu 20.04

Solution 1:

Don't use gcc-5, that causes ubuntu to specifically look for GCC 5.x, which is years out of date and not installed on most systems. Just use 'gcc' as the command, which will delegate to the default, installed gcc version (in your case, 9.3).

If you're following a guide that tells you to run a script, find a new guide or edit the script.

Solution 2:

The fix I found was to just do this

ln -s /bin/gcc /bin/gcc-5

    
$ ln -s /bin/gcc /bin/gcc-5
$ pip3 install netifaces
Collecting netifaces
  Using cached netifaces-0.10.9.tar.gz (28 kB)
Using legacy 'setup.py install' for netifaces, since package 'wheel' is not installed.
Installing collected packages: netifaces
    Running setup.py install for netifaces ... done
Successfully installed netifaces-0.10.9

I hope this helps you.
