Fail to install mpc

[niezifei]

Hi, The mpc package (version 0.0.4) specifies its dependency on numpy in a non-standard way, which will cause problems with future versions of pip. The current dependency specifier is written as numpy>=1<2, which is not a valid format.

The standard way to specify the dependency should be numpy>=1.0,<2.0.

Collecting mpc
  Using cached mpc-0.0.4.tar.gz (17 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py egg_info did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.

Hi Fei, I wonder have you solve this issue? I am facing the same issue too.

Manually install it by pip install -e . solved this issue.
