Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-yrbji133/pomegranate/

This is on Arch Linux, but I suspect the same error is happening on all platforms.

I am running into a possibly similar problem
"pip3 install pomegranate."

The error does not occur if I run "pip3 install pomegranate==0.10"

Error pasted below:

I just added new mac and linux wheels to the repo, which should circumvent this issue. Making a new python3.6 virtual environment, I'm able to pip install pomegranate with no issues. Can you confirm?

[Wesserg]

Works for me. Thanks!

[jmschrei]

Awesome, thanks for pointing the issue out!

[alexhenrie]

It's working for me now too. Thank you!

Thanks, I use pip install pomegranate==0.10 and solve the problem.

I was getting the same issue..
I did pip3 install cython followed by pip3 install pomegranate ...

It worked.

[yanpanlau]

Thanks. Doing pip install cython solve the problem

[zachwill]

I can also confirm that this fixed my issue, too:

pip install cython
pip install pomegranate
