Installation with pip-20.1 failed

Hi,
I tried to do the installation of illumina-utils for anvio with pip-20.1.
The following error came up.

Using cached illumina-utils-2.7.tar.gz (3.3 MB) ERROR: Command errored out with exit status 1: command: /Users/virtual-envs/anvio-master/bin/python -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-install-n0dzn60q/illumina-utils/setup.py'"'"'; __file__='"'"'/private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-install-n0dzn60q/illumina-utils/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-pip-egg-info-y_xa8czy cwd: /private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-install-n0dzn60q/illumina-utils/ Complete output (7 lines): Traceback (most recent call last): File "<string>", line 1, in <module> File "/private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-install-n0dzn60q/illumina-utils/setup.py", line 17, in <module> reqs = [str(ir.req) for ir in install_reqs] File "/private/var/folders/_b/40l3prb52ln490d96qf4ccmh0000gn/T/pip-install-n0dzn60q/illumina-utils/setup.py", line 17, in <listcomp> reqs = [str(ir.req) for ir in install_reqs] AttributeError: 'ParsedRequirement' object has no attribute 'req' ---------------------------------------- ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

I downgraded pip to pip-19.3 and the installation worked without any problems.

Same problem with newer pip versions(mine is 20.3.3).
Checked advice of @DennisJakob and it worked.

Thank you for the heads-up, @ISonets!
