Windows 7上使用Python 2.7。下面是我用来安装和错误消息的命令。 想知道有没有人遇到过类似的问题? 谢谢。

从上面的位置获取matplotlib。 根据python(2.x / 3.x)和bit(32/64)版本选择正确的软件包。

 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,请参阅下面的链接: https : //stackoverflow.com/a/38618044/5334188

我通过1.5.1版本解决了这个问题

 pip install matplotlib==1.5.1 

似乎版本1.5.2安装程序已损坏。

正如你可以看到它pngfreetype模块丢失。 您需要分别安装它们。

尝试执行以下操作:

 > pip install freetype-py > pip install pypng > pip install matplotlib 

我有完全相同的问题。

似乎我的点子是旧的v7。 通过“升级”按钮升级到v9。 然后试图再次安装matplotlib,这次是成功的。

也许这有帮助

我遇到同样的问题,这是我的解决方案

它与Python 3.6集成最新的点的问题。 所以我用pip安装了python 3.5.2,但是不要升级pip。 你可以用这种方式安装matplotlib。

希望我能提供一个可能的解决方案
