在Windows 7上使用Python 2.7。这是我用来安装的命令和错误信息。不知道以前有没有人遇到过类似的问题?谢谢。

您可以看到png和freetype模块缺失。您需要单独安装它们。
试着这样做:
> pip install freetype-py
> pip install pypng
> pip install matplotlib
我用1.5.1版本解决了这个问题
pip install matplotlib==1.5.1
http://www.lfd.uci.edu/~gohlke/pythonlibs/
从上述位置获取matplotlib。根据python(2.x/3.x)和bit(32/64)版本选择正确的包
32-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win32.whl
64-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win_amd64.whl
如果您在中间遇到任何问题，请参考以下链接:https://stackoverflow.com/a/38618044/5334188
我也有同样的问题。
似乎我的pip是v7，是旧的。使用"升级"按钮升级到v9。然后再次尝试安装matplotlib，这次成功了。
也许这有帮助
我也遇到过同样的问题，下面是我的解决方案
它有python 3.6与最新的pip集成的问题。所以我安装了python 3.5.2与pip，但没有升级pip。您可以通过这种方式安装matplotlib。
希望我能提供一个可能的解决方案
我在Wİndows 10解决了同样的问题，如下所示:
1- win32或win64 python3.7下载以下文件:
matplotlib-2.2.2-cp27-cp37m-win32.whl
或
matplotlib-2.2.2-cp27-cp37m-win_amd64.whl
from https://www.lfd.uci.edu/~gohlke/pythonlibs/
2-通过cmd控制台在python下运行下载的文件:
.Downloads> python -m pip install matplotlib-2.2.2-cp37-cp37m-win_amd64.whl
你可以试试matplolib
我今天有这个问题与Python 3.8.0和matplotlib==3.2.0rc1安装成功后，我安装了freetype-py。
在Windows 10上安装特定的matplotlib 2.2.5版本对我来说是正常的。
通过pip安装特定版本的命令:
pip install matplotlib==2.2.5
