Python 如何从 CMD 运行 Pip 命令

How to run Pip commands from CMD

提问by algorhythm

As I understand, Python 2.7.9 comes with Pip installed, however when I try to execute a Pip command from CMD (Windows) I get the following error:

据我了解，Python 2.7.9 安装了 Pip，但是当我尝试从 CMD (Windows) 执行 Pip 命令时，出现以下错误：

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

When I type pythonI do get the following, which suggests it has been installed correctly:

当我输入时，python我确实得到以下信息，这表明它已正确安装：

Python 2.7.9 (default, Dec 10 2014, 12:24:55) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

I did however need to add some environmental variables to get the python part working on CMD:

然而，我确实需要添加一些环境变量才能让 python 部分在 CMD 上工作：

• Add to the environment variable PATH: "C:\Python27\"

• Define the system variable PYTHONPATH: "C:\Python27\"

• 添加到环境变量PATH："C:\Python27\"

• 定义系统变量PYTHONPATH："C:\Python27\"

I cannot find a Pip folder within the Python directory, however there is a folder called "ensurepip" in C:\Python27\Lib\.

我在 Python 目录中找不到 Pip 文件夹，但是在C:\Python27\Lib\.

Does anybody know how can I get Pip commands to start working in CMD?

有人知道如何让 Pip 命令开始在 CMD 中工作吗？

Little side note for anyone new to Python who didn't figure it out by theirself: this should be automaticwhen installing Python, but just in case, note that to run Python using the pythoncommand in Windows' CMD you must first add it to the PATHenvironment variable, as explained here.

对于没有自己弄清楚的 Python 新手来说，这应该是自动的，但为了以防万一，请注意，要使用pythonWindows 的 CMD 中的命令运行 Python ，您必须首先将其添加到PATH环境变量，如解释here。

To execute Pip, first of all make sure you have it. So type in your CMD:

要执行 Pip，首先要确保你拥有它。所以输入你的CMD：

> python
>>> import pip
>>>

And it should proceed with no error. Otherwise, if this fails, you can look hereto see how to install it. Now that you are sure you've got Pip, you can run it from CMD with Python using the -m(module) parameter, like this:

它应该没有错误地继续。否则，如果此操作失败，您可以在此处查看如何安装它。现在您确定您已经获得了 Pip，您可以使用-m(module) 参数从 CMD 使用 Python 运行它，如下所示：

> python -m pip <command> <args>

Where <command>is any Pip command you want to run, and <args>are its relative arguments, separated by spaces.

<command>你想运行的任何 Pip 命令在哪里，以及<args>它的相对参数，用空格分隔。

For example, to install a package:

例如，要安装一个包：

> python -m pip install <package-name>

Make sure to also add "C:\Python27\Scripts" to your path. pip.exe should be in that folder. Then you can just run:

确保还将“C:\Python27\Scripts”添加到您的路径中。pip.exe 应该在该文件夹中。然后你可以运行：

C:\> pip install modulename

Firstly make sure that you have installed python 2.7 or higher

首先确保你已经安装了 python 2.7 或更高版本

Open Command Prompt as administrator and change directory to python and then change directory to Scripts by typing cd Scripts then type pip.exe and now you can install modules Step by Step:

以管理员身份打开命令提示符并将目录更改为 python，然后通过键入 cd Scripts 将目录更改为 Scripts，然后键入 pip.exe，现在您可以逐步安装模块：

• Open Cmd

• type in "cd \" and then enter

• type in "cd python2.7" and then enter

• 打开命令

• 输入“cd \”，然后输入

• 输入“cd python2.7”然后输入

Note that my python version is 2.7 so my directory is that so use your python folder here...

请注意，我的 python 版本是 2.7，所以我的目录是这样的，所以在这里使用你的 python 文件夹......

• type in "cd Scripts" and enter

• Now enter this "pip.exe"

• Now it prompts you to install modules

• 输入“cd Scripts”并输入

• 现在输入这个“pip.exe”

• 现在它会提示你安装模块
