Hello all,
pip install pycupid in my computer returns the following errors (both in Ubuntu 18.04 and MacOS Mojave):

Tried download the package and pip install .
Failed either with plenty of errors.

Any suggestions? Thanks a lot!

Same problem for me. Installing from source with

git clone https://github.com/ChileanVirtualObservatory/pycupid.git
python setup.py build install

fails with the error

error in pycupid setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Unordered types are not allowed

The third option using

pip install git+https://github.com/ChileanVirtualObservatory/pycupid.git

also fails with another error message

ERROR: Command errored out with exit status 1: git submodule update --init --recursive -q Check the logs for full command output.

This package is not useable! Please fix.

The various installation methods work just fine if run in the correct python version (2.7, 3.4, 3.5, 3.6). Version 3.7+ are not supported.
Installation attempts on unsupported version should be prevented with PR #18.
