Can't install with pip?

[joshburkart]

This seems like a great module! I love clean APIs like you seem to have implemented. Unfortunately pip seems to give me errors when trying to install; any ideas?

Hey did you fix this?

python3.5 does not work. Change your paython to 3.4

Rolling back the Python version is not a sensible solution. It doesn't seem too hard to simply fix the bug in setup.py. Using ez-setup.py is no longer the recommended way to writing a setup script which rely on setuptools.

pip3 install ddeint seems to work for me (python 3.6). Maybe this is something specific to python 3.5 (at which case it's not worth a fix). Are we sure this is even linked to ez_setup, and not to a system rights problem ?

[fccoelho]

it failed for me on python 3.6:

sudo -H pip3 install -U ddeint
[sudo] senha para fccoelho:

        import ez_setup
    ModuleNotFoundError: No module named 'ez_setup'

And it does seem to be an issue with ez_setup.py

I would just delete the first two lines of
https://github.com/Zulko/ddeint/blob/master/setup.py

and make sure you have setuptools installed on your system before installing the package.
By the way I believe that if you have pip installed you must have setuptools as well.

[Zulko]

Ok that actually sounds like a MANIFEST.in issue (the ez_setup.py file was missing from the manifest so not shipped with the library).

I hear you regarding the deprecation of ez_setup, but it should still work with it.

[sarahsama]

It is possible to install by pip too. pip3 install Charm-Crypto
