推荐答案

虽然 Kugel 的回答 是完全有效的，但我会还敦促您避免系统范围的安装，并使用 virtualenv.它将允许您为您的项目创建一个沙箱并将其与其他人隔离.

While Kugel's answer is perfectly valid, I would also urge you to avoid system wide install, and to use a virtualenv. It will allow you to create a sandbox for your project and isolate it from others.

创建 virtualenv 时，您可以指定要使用的 Python 解释器版本.例如，对于python2.7:

When creating a virtualenv, you can specify the Python interpreter version you want to use. For example, for python2.7:

$ virtualenv path/to/project -p /usr/bin/python2.7

然后，一个pip install命令会自动安装python2.7的包.

Then, a pip install command will automatically install the package for python2.7.
