我无法获得最新版本的pip

Question

当我尝试使用命令提示符升级我的点，到最新版本时，我得到下图中的错误。是否有一个我忽略的行政步骤？

我的命令提示符的图像位于此链接（我没有包含图像所需的10的声誉）。

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

看来你正在使用Anaconda。在这种情况下，您应该使用conda命令更新pip：

conda update pip

如果不起作用，请尝试以管理员身份打开cmd.exe，然后重试。
