[Python 3.5] Installation fails - Workaround avaible

[MarvinTeichmann]

When running 'python setup.py install' on my machine I get the error message below.

The error indicates, that the code of test/test.py fails. The reason for this is, that test loads the local module '.encoding' instead of the installed one. A possible workaround is to run python setup.py build_ext --inplace before running python setup.py install. This creates a compiled lib inside the local module.

I assume that the author has run the former command at some point, so that he does not run into the issue. I think however, that this should ether be documented [hacky solution], of fixed in the sense that test.py should load the installed module and not the local one.
