我最近买了一台新笔记本电脑，我想安装所有的python库。但是，其中一些不会像matplotlib那样安装。
关于我的电脑：使用Python 3.6的Windows 10，以及pip，这些库。
colorama (0.3.7)
Django (1.8.17)
Mathics (1.0)
mpmath (0.19)
pip (9.0.1)
python-dateutil (2.6.0)
setuptools (32.3.0)
six (1.10.0)
sympy (1.0)
wheel (0.29.0)
“pip install matplotlib”的结果：

基本上，关于缓存文件，来自site.py的一堆AttributeErrors以及没有freetype或png的东西。我试图修复site.py，但它仍然无法正常工作。我尝试了PyPi的.whl文件，但这不起作用。我试过“pip install matplotlib --no-cache-dir”，同样的事情。我尝试手动下载png和freetype，但我找不到它们。与我想下载的所有其他库大致相同的事情发生：NumPy，SciPy，pandas。

1.5.1版本没有这个问题，可以查看一下：
from IPython.display import Latex
B=1.0e5 # in Gauss
fce = 1.80e6 * B
Latex("Electron gyrofrequency $f_{ce}$= %0.5e " % fce)

如果您在Python 3.6中使用anaconda，则可以使用：
conda install -c conda-forge python=3.6.0
conda install matplotlib --channel conda-forge
要下载anaconda，请访问https://www.continuum.io/downloads

和你一样，我绕着这个圈子走了一圈！
如果从PyPI安装，则应该没问题。我使用了matplotlib-2.0.0rc2-cp36-cp36m-win32.whl，但也有64位版本。
我使用cmd.exe“以管理员身份运行”安装我的路径中的python目录：
pip3 install matplotlib-2.0.0rc2-cp36-cp36m-win32.whl
