它在windows中是这样工作的:

我将python文件的名称python.py和pythonw.exe更改为python3.py pythonw3.py 然后我在提示符中运行这个命令: Python3 -m PIP安装包

下面是如何为同时安装的linux, mac, posix的不同版本安装包:

python2   -m pip install SomePackage  # default Python 2
python2.7 -m pip install SomePackage  # specifically Python 2.7
python3   -m pip install SomePackage  # default Python 3
python3.4 -m pip install SomePackage  # specifically Python 3.4
python3.5 -m pip install SomePackage  # specifically Python 3.5
python3.6 -m pip install SomePackage  # specifically Python 3.6

在Windows上，将py Python启动器与-m开关结合使用:

py -2   -m pip install SomePackage  # default Python 2
py -2.7 -m pip install SomePackage  # specifically Python 2.7
py -3   -m pip install SomePackage  # default Python 3
py -3.4 -m pip install SomePackage  # specifically Python 3.4

/ / python2 /路径。{5,6} /path/to/pip install PackageName不正常?

为了在任何没有安装pip的python版本上工作，你需要下载pip并执行python*version* setup.py install。例如python3.3 setup.py install。这解决了注释中的导入错误。(@hbdgaf建议)

目前建议使用python -m pip，其中python是您想使用的python版本。这是推荐的，因为它适用于所有版本的Python和所有形式的virtualenv。例如:

# The system default python:
$ python -m pip install fish

# A virtualenv's python:
$ .env/bin/python -m pip install fish

# A specific version of python:
$ python-3.6 -m pip install fish

之前的答案，留给后人:

从0.8版本开始，Pip支持Pip -{version}。你可以像easy_install-{version}一样使用它:

$ pip-2.5 install myfoopackage
$ pip-2.6 install otherpackage
$ pip-2.7 install mybarpackage

编辑:在1.5版中，pip将其模式更改为使用pipVERSION而不是pip- version。如果你的pip >= 1.5，你应该使用以下命令:

$ pip2.6 install otherpackage
$ pip2.7 install mybarpackage

显然，easy_install和pip有多个版本。看起来很乱。不管怎样，这是我在Ubuntu 12.10上安装Django for Python 2.7的方法:
