python - 如何使用setuptools安装到自定义目录？

Question

我有一个 Python 包，我需要将其安装在 /usr/lib/python2.7/dist-packages 或与此相关的任何其他特定目录中。

每当我运行 setup.py 脚本时，它都会给出以下输出:

有没有办法在setuptools中指定包的安装目录？我尝试了 --install-dir 选项，但它给出了一个错误:

$sudo python setup.py install --install-dir=/usr/lib/python2.7/dist-packages
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: option --install-dir not recognized

我也无法使用 --prefix 选项。

由于python setup.py install命令只是easy_install的快捷方式，尝试直接运行它，它有--install-dir选项:

easy_install . --install-dir /usr/lib/python2.7/dist-packages

您可以使用 python setup.py install -h 获得其他可用选项，以备不时之需，但这些选项相当神秘。
