Python Pip安装：未识别为批处理文件。。。。在命令提示窗口中

我有一个项目，需要安装numpy

就在今天早上，我将Python2.7.11下载到了我的Windows10计算机上，自从下载之后，我就没有在2.7.11安装中使用过pip或其他任何东西

我没有移动安装2.7.11中的任何文件

我打开命令提示符并键入

pip install numpy

并得到了错误信息：

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

接下来，我提出：

cd C:\Python27\Scripts

进入命令提示符。它响了，我又打了一次：

pip install numpy

它工作了一段时间，下载numpy没有问题。然后：

C:\Python27\Scripts>pip install numpy

或者类似的东西。（就像我说的，找不到那篇文章）

得到了这个错误：

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

任何帮助都会很好！ 如果你有一种不用pip下载numpy的方法，那就太好了，但是我还需要一些其他模块，我真的很想让pip正常工作。 另外，我的互联网非常糟糕，避免下载大量文件会很有帮助

谢谢

有三种方法可以解决这个问题

您忘了执行

C:/Python27/python get pip.py

。您记得为

pip

这样做，但放弃了

python get pip.py

< P>也需要C++，它是在错误的最后一行上所说的。代码>错误：需要微软Visual C++ 9（无法找到VCVALSALAL.BAT）。从http://aka.ms/vcpython27。正如它所说的，得到Visual C++。没有它，皮普就不能工作

如果总是键入

C:/Python27/python

和

C:/Python27/Scripts/pip

而感到烦恼，请编辑PATH环境变量。你可以用谷歌搜索。进入后，键入目录（例如

C:/Python27/python

）。所有目录都用分号分隔

---

如果这有帮助的话，添加一个+1

在windows上，改为安装二进制文件。签出或编辑PATH环境变量以包含python位置…Windows用户的另一个极好的选择是安装PATH环境变量。PATH环境变量是系统中的一个设置，它允许在列出的目录中运行

.exe

，只需绑定

.exe

（不带扩展名！）谢谢你的回答。正如我所说，我有非常慢的互联网，所以我不知道是否VisualC++是唯一的问题，虽然它看起来是有可能的（并且，如果你看看我的名声，在这一点上，我完全没有，所以我现在不能+ 1）在Windows上，PIP是用Python 2.7分发，所以不需要运行GET-PI.py..

PATH

搜索任何文件，而不仅仅是.exe文件。cmd shell还将尝试使用附加的

PATHEXT

中的每个扩展名进行搜索，直到找到匹配项。在Windows API中，

CreateProcess

和

LoadLibrary

也有一个部分基于

path

的搜索路径。如果省略扩展名，它们会将默认值分别硬编码为“.EXE”和“.DLL”。
