UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 33: invalid continuation byte

Question

I've been having problems installing matplotlib toolkit for my python. After giving the command pip install basemap-1.1.0-cp36-cp36m-win32.whl to my windows command promt, the install begins shortly and runs for a while, but after that, it stops and just gives me the following message:

Exception:
Traceback (most recent call last):
  File "c:\users\lasse\appdata\local\programs\python\python36-32\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 33: invalid continuation byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "c:\users\lasse\appdata\local\programs\python\python36-32\lib\site-packages\pip\basecommand.py", line 215, in main

    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 33: invalid continuation byte.

I tried to look for answer, but everything I could find had nothing to do with installing, but with code that was written by the user itself, so I got no clue how to apply that information to my case.

Answer 1

Do pip install matplotlib

You are installing specific version of a dependency of matplotlib. But the above command will automatically install any dependency of supported version. Which will be specific to your python version.
