自定义 distutils 命令 [英] Custom distutils commands

问题描述

我有一个名为example"的库，我将它安装到我的全局站点包目录中.但是，我希望能够安装两个版本，一个用于生产，一个用于测试(我有一个网络应用程序和其他以这种方式进行版本控制的东西).

I have a library called "example" that I'm installing into my global site-packages directory. However, I'd like to be able to install two versions, one for production and one for testing (I have a web application and other things that are versioned this way).

有没有办法指定，比如python setup.py stage"，它不仅可以将不同的 egg 安装到站点包中，还可以将模块从example"重命名为example_stage"或类似的东西?

Is there a way to specify, say "python setup.py stage" that will not only install a different egg into site-packages, but also rename the module from "example" to "example_stage" or something similar?

如果 distutils 不能做到这一点，有没有其他工具可以做到这一点?

If distutils cannot do this, is there any other tool that can?

推荐答案

当然，您可以使用新命令扩展 distutils.在您的 distutil 配置文件中，添加:

Sure, you can extend distutils with new commands. In your distutil configuration file, add:

 [global]
 command-packages=foo.bar

这可以在 distutils 包本身的 distutils.cfg 中，..pydistutils.cfg 在你的主目录中(没有前导点在 Windows 上)，或当前目录中的 setup.cfg.

this can be in distutils.cfg in the distutils package itself, ..pydistutils.cfg in your home directory (no leading dot on Windows), or setup.cfg in the current directory.

那么你需要在你的 Python 的 site-packages 目录中有一个 foo.bar 包.

Then you need a foo.bar package in your Python's site-packages directory.

然后在该包中添加实现新所需命令的类，例如 stage，子类化 distutils.cmd -- 文档很弱，但有很多例子，因为所有现有的 distutils 命令也是这样构建的.

Then in that package you add the classes implementing your new desired commands, such as stage, subclassing distutils.cmd -- the docs are weak, but there are plenty of examples since all the existing distutils commands are also built that way.
