Installing Package Halo Gives Error: 'install_requires' Must Be A String Or List Of Strings Containing Valid Project/version Requirement Specifiers

Im trying to install Halo by using, pip install halo I get the following error message: ERROR: Command errored out with exit status 1: command: /usr/bin/python -c 'impor

Solution 1:

It looks like it's a known bug for that package:

You just have to update setup tools via: pip install -U setuptools

If that doesn't work, try adding the --user flag: pip install --user -U setuptools

Solution 2:

Try this command

pip3 install --user package-name  # for Python3
pip install -U setuptools && pip install halo  # for Python3

pip install --user package-name   # for Python2
pip3 install -U setuptools && pip install halo # for Python2
