如何使用Windows版pip在不同的python安装中安装模块

Question

I'm trying to create a standalone executable with PyInstaller. I currently have Python 3.4 which is not supported by PyInstaller. I downloaded Python 2.7 but now I am not able to install PyInstaller with pip. I set the path variable to C:/Python24 but I still get this message when I type python pip into the command console.

Requirement already up-to-date: pip in c:\\python34....

When I use the commands:

echo %PATH% 
python pip.py 

I get the output:

c:\\mingw\\bin;C:\\Program Files\\Java\\jdk1.7.0_25\\bin;c:\\windows\\system32;c:\\Python34;C:\\Program Files (x86)\\ATI Technologies\\ATI.ACE\\Core-Static;C:\\Program Files (x86)\\Windows Kits\\8.1\\Windows Performance Toolkit\\;C:\\Program Files\\Microsoft SQL Server\\110\\Tools\\Binn\\;C:\\Program Files (x86)\\Microsoft SDKs\\TypeScript\\1.0\\;C:\\Program Files\\Microsoft SQL Server\\120\\Tools\\Binn\\;C:\\Ruby193\\bin;C:\\Program Files\\Java\\jdk1.8.0_05\\bin;C:\\Python27;C:\\Python27\\Scripts;C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC

Requirement already up-to-date: pip in c:\\python34\\lib\\site-packages

Answer 1

To install pip for Python 2.7 run the get-pip.py (you can get it here for example) script using Python 2.7 interpreter:

> C:\\Python27\\python.exe get-pip.py

Downloading/unpacking pip

Installing collected packages: pip

Successfully installed pip

Cleaning up...

> C:\\Python27\\Scripts>c:\\Python27\\Scripts\\pip.exe

Usage:

pip <command> [options]

[...]

To run scripts from a particular Python distribution go to their directory in the console:

Typically:

> C:

C:\\......\\

> cd \\Python27\\Scripts

C:\\Python27\\Scripts

> pip or easy_install or whatever

If you want to have it in PATH, then the Scripts subdirectory is the one to add, not just Python's root directory. Also be sure to remove any other occurrences of Python paths in this variable (in both system and user PATH settings).

Alternatively, you can just download the package directly (eg for PyInstaller: https://pypi.python.org/pypi/PyInstaller/2.1 ).
