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 wrapt (from astroid>=1.5.1->pylint)
Using cached wrapt-1.10.11.tar.gz
Installing collected packages: colorama, wrapt, astroid, pylint
Running setup.py install for wrapt ... error
Exception:
Traceback (most recent call last):
File "C:\Users\(...)\AppData\Local\Programs\Python\Python36\lib\site-packa
ges\pip\compat\__init__.py", line 73, in console_to_str
return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 51:
invalid start byte
Obviously, something causes some "s" to be decoded using the "stdout" encoding
(which usually is the system encoding). In your case, this encoding is "utf-8",
but "s" does not seem to be utf-8 encoded.
I would use debugging to find out what "s" is, where is comes from and why it
does not use the "stdout" encoding.
I don't know how to use pdb. Instead, I've added the following
instruction at line 73 before the error occurs:
print("!! TEST !! : ", s)
Here's the output now:

Apparently _wrappers.c is compiled with MSVC but the Python script
managing the installation can't handle a warning from MSVC containing a
special character. _wrappers.c is deleted right after the installation
fails so I can't look into it.
Also wrapt's setup.py doesn't recognize the command "bdist_wheel" ...
I can't go much further than that.
