无法安装matplotlib

Question

Problem: Unable to install matplotlib v 2.02 in Python 3.3 on Windows 10 environment

C:\Python33>pip install matplotlib

The pip installer completes most of the task and then gives me this error

Command "python setup.py egg_info" failed with error code 1 in c:\users\xxx\appdata\local\temp\pip-build-3ob70y\matplotlib\


C:\Python33>pip install --upgrade setuptools

Requirement already up-to-date: setuptools in c:\python33\lib\site-packages

I have tried the following

• uninstalling and reinstalling
• doing this at the root rather than Python33 folder

• manually installing maplotlib. this seemed to work but it then found two missing files (__ and cycler) . I installed those separately with pips but then it complained about six.moves being missing

• consulting Can't install via pip because of egg_info error

• consulting several other articles on web. Some suggested a conflict between the requirements of python 2 and pythono 3. However it seems the packages are supposed to work with both

Here is the detailed pip error message

Answer 1

As the official version of Matplotlib in Python package index https://pypi.python.org/pypi/matplotlib/ , it supports only the following Python versions:

• Python :: 2.7
• Python :: 3.4
• Python :: 3.5
• Python :: 3.6

So, you can not install matplotlib 2.1.0rc1 (which is the version you get using pip install matplotlib ) in Python 3.3.
