Pip error:should upgrade pip, pandas and matplotlib but returns error
我必须卸载Python 3.6.1并安装3.5.0，因为这是唯一适用于TensorFlow的版本。 我正确地更改了路径，并且在成功安装第一个软件包(numpy)之后，出现了此错误(前两行)。 我试图按照它所说的做，并且发生错误(下)，并且还尝试安装pandas和numpy(abowe)：

我尝试下载轮，然后安装它：
1 2 3 | C:\\Users\\Downloads>pip install matplotlib-2.0.2-cp36-cp36m-win32.whl matplotlib-2.0.2-cp36-cp36m-win32.whl is not a supported wheel on this platform. |
也尝试了64 bt版本，相同的故事。
有什么想法该做什么，这甚至意味着什么？

如何使用pip一次安装多个python软件包
从此站点下载所需的所有模块http://www.lfd.uci.edu/~gohlke/pythonlibs/
只需下载whl文件，然后在文件所在的文件夹中pip安装filename.whl。希望这对您有所帮助。
这个问题已经成为一个新问题，因此需要一个新的答案。解决了逗号问题后，您的系统开始大吼大叫，因为matplotlib依赖于pip如果不将源代码编译为二进制(即freetype和png)就无法安装的软件包。从理论上讲，您可以设置一个编译器并全力以赴，但这对我们大多数人来说都是一个真正的痛苦。
问题的答案是完全清除python安装并重新开始。这次，安装Anaconda python发行版，而不是pip安装matplotlib，而是使用conda安装matplotlib。实际上，如果您安装了完整的Anaconda发行版，则matplotlib将已经存在。
Anaconda的优点在于，它们可以跟踪大量预编译的软件包，因此您不必担心像在pip中那样构建所有这些东西。
如果您不想这样做，并希望保留当前的python设置，则可以从Christopher Gholke网站下载所有轮子，然后使用pip安装轮子。这些软件包包含您需要的编译二进制文件，这些二进制文件无法直接从PyPI获得

键入
输入：
1 | python -m pip install --upgrade pip |
然后安装所需的内容：
1 | pip install pandas matplotlib |
