Python Pip 安装：无法识别为批处理文件....在命令提示符中 windows

Question

我有一个项目需要安装numpy。

我今天早上刚把 Python 2.7.11 下载到我的 windows 10 电脑上，自从下载后就没有在 2.7.11 安装中使用 pip 或其他任何东西。

安装2.7.11我没有移动任何文件。

我打开命令提示符并输入

pip install numpy

并得到错误：

 pip is not recognized as an internal or external command, operable program or batch file

接下来，我输入：

cd C:\Python27\Scripts

进入命令提示符。它去了，我再次输入：

pip install numpy

它工作了一段时间，下载 numpy 没有问题。那么：

C:\Python27\Scripts>pip install numpy

这实际上是我重试安装的时候，这就是为什么一开始它说 "using cached numpy-1.10.2.tar.gz"

我不知道所有这些错误是什么意思，但我在某处看到一篇文章（在我无法重新找到的地方，所以我无法给出 link）说要安装通过在命令提示符中输入 pip:

python get-pip.py

或类似的东西。（正如我所说，无法重新找到那篇文章）

并收到此错误：

"python" is not recognized as an internal or external command, operable program or batch file

任何帮助都会很棒！如果您有一种无需 pip 即可下载 numpy 的方法，那会很棒，但我还有一些其他模块需要获取，我真的很想让 pip 工作。另外，我的网络非常糟糕，这有助于避免下载大文件。

谢谢

有 3 种方法可以解决这个问题。

您忘记了 C:/Python27/python get-pip.py。您记得 pip 时这样做了，但您在 python get-pip.py 时放弃了。
另外，你需要C++，它在你的错误的最后一行说了。 error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27。正如它所说，获取 Visual C++。没有它，Pip 无法工作。
如果您对总是输入 C:/Python27/python 和 C:/Python27/Scripts/pip 感到困扰，请编辑您的 PATH 环境变量。你可以 Google 那。进入后，输入您的目录（例如 C:/Python27/python）。所有目录都用分号分隔。

如果这有帮助，请加 1！
