Hi,
I have trouble installing pylint on Windows 10, Python 3.6. There's a
problem during the installation of wrapt, which is a dependency of pylint.
Here are the contents of the commandline:
C:\WINDOWS\system32>python -m pip install pylint
Collecting pylint

The same problem happens from a venv.
I have reinstalled Python 3.6.3 and 3.6.4rc1 several times, that didn't
change anything.
Note that the installation of pylint was reported to be successful a few
times but despite that, pylint was unusable: when I tried to use pylint
an error message said that module wrapt.wrappers couldn't be found.
Since the wrapt module seemed to be incorrectly installed I uninstalled
it. I don't know how I managed to get passed the above error message a
couple of times when installing pylint.
I would appreciate any help.
