Unicode decode error when put coverage into setup script in Windows

I am using Windows 10 with Anaconda 64 bit python 3.5. It seems I can't put coverage as part of a requirement in any setup scripts.

For example, running the following setup script will fail:

#!python

from setuptools import setup

setup(
    name='testpackage',
    version='1.0',

    author_email='',
    long_description="HelloWorld",
    license='BSD',
    classifiers=[],
    install_requires=[
        'pytz',
        'coverage'
    ],
)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x90 in position 2: invalid start byte

Any thoughts?

By revmoing "coverage" in the setup script, the install script pass.

Hmm, I have no idea why that would happen. I don't know where there's a 0x90 byte in the coverage.py metadata.

Is there any way you could debug into pkg_resources_init_.py to see what it's looking at?

I got the same error on windows 10 pro using Miniconda in a virtual env.
conda version: 4.3.22
python version: 3.6.1

Also, removing coverage in the install requires fixes the issue. Installing coverage through pip before calling the setup fixes the issue also.
There is an issue on setuptools about that : pypa/setuptools#819

@fgoudreault thanks for the link to the pypa issue. I didn't know about that one. It mentions easy_install. Can you show the specific commands you are using to run the installation? @chinux23 What commands did you use to install?

I used python setup.py develop where setup.py looks like:

#!python

from setuptools import setup
import versioneer

setup(name="name",
      description="description",
      url="url",
      install_requires=["nose", "pep8", "coverage", "openpyxl"],
      version=versioneer.get_version(),
      cmdclass=versioneer.get_cmdclass())

@fgoudreault does "pip install -e ." work for you?

Yes, pip install -e seems to work.
