如何使用 setuptools 安装在自定义目录中? [英] How to use setuptools to install in a custom directory?

问题描述

我有一个 Python 包，我需要将它安装在 /usr/lib/python2.7/dist-packages 或任何其他与此相关的特定目录中.

I have a Python package that I need to install in the /usr/lib/python2.7/dist-packages or any other specific directory for that matter.

每当我运行 setup.py 脚本时，它都会给出以下输出:

Whenever I run the setup.py script it gives the following output:

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:

Is there any way to specify the install directory of the package in setuptools? I tried --install-dir option but it gives an error:

$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

我也不能使用 --prefix 选项.

I could not use --prefix option also.

推荐答案

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

Since the python setup.py install command is just a shortcut to easy_install, try running it directly, it has the --install-dir option:

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，以防您需要更多选项，但这些选项相当神秘.

You can get other available options with python setup.py install -h, in case you need some more, but these are rather cryptic.
