'pip'不被识别为内部或外部命令 [英] 'pip' is not recognized as an internal or external command

问题描述

这是我输入到我的命令行的顺序：

  C：\Python34> python get-pip.py 
要求已经最新：pip in c： \python34\lib\site-packages 
清理... 
 
 C：\Python34>点安装Django 
'pip'不被识别为内部或外部命令
可操作的程序或批处理文件。 
 
 C：\Python34> lib\site-packages\pip安装Django 
'lib \site-packages\pip'不被识别为内部或外部命令， 
可操作的程序或批处理文件。 
  

可能导致这种情况？

解决方案

您需要将pip安装路径添加到PATH系统变量中。默认情况下，pip安装到 C：\Python34\Scripts\pip （pip现在附带新版本的python），所以路径C：\\ \\ Python34\Scripts需要添加到您的PATH变量中。

要检查它是否已经在您的PATH变量中，请键入 echo％在CMD提示符下的PATH％

要将点阵安装的路径添加到PATH变量，您可以使用控制面板或 setx 命令。例如：

  setx PATH％PATH％; C：\Python34\Scripts

注意：
根据< a href =https://technet.microsoft.com/en-us/library/cc755104%28v=ws.11%29.aspx>官方文档，[v]设置setx变量的ariables是仅在将来的命令窗口中可用，不在当前命令窗口中。特别地，在输入上述命令后，您将需要启动一个新的cmd.exe实例，以便使用新的环境变量。

感谢Scott Bartell指出这一点。

I'm running into a weird error trying to install Django on my computer.

This is the sequence that I've typed into my command line:

C:\Python34>python get-pip.py
Requirement already up-to-date: pip in c:\python34\lib\site-packages
Cleaning up...

C:\Python34>pip install Django
'pip' is not recognized as an internal or external command,
operable program or batch file.

C:\Python34>lib\site-packages\pip install Django
'lib\site-packages\pip' is not recognized as an internal or external command,
operable program or batch file. 

What could be causing this?

As requested this is what I get when I type in echo %PATH%

解决方案

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to C:\Python34\Scripts\pip (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.

To check if it is already in your PATH variable, type echo %PATH% at the CMD prompt

To add the path of your pip installation to your PATH variable, you can use the Control Panel or the setx command. For example:

setx PATH "%PATH%;C:\Python34\Scripts"

---

Note: According to the official documentation, "[v]ariables set with setx variables are available in future command windows only, not in the current command window". In particular, you will need to start a new cmd.exe instance after entering the above command in order to utilize the new environment variable.

Thanks to Scott Bartell for pointing this out.
