Python:如何编辑已安装的包? [英] Python: how to edit an installed package?

问题描述

我通过 pip install something 安装了一些包.我想编辑包 something 的源代码.它在哪里(在 ubuntu 12.04 上)以及如何在每次编辑源代码并运行它时重新加载它?

I installed some package via pip install something. I want to edit the source code for the package something. Where is it (on ubuntu 12.04) and how do I make it reload each time I edit the source code and run it?

目前我正在编辑源代码，然后一遍遍运行python setup.py，结果很麻烦.

Currently I am editing the source code, and then running python setup.py again and again, which turns out to be quite a hassle.

推荐答案

您不应该编辑已安装的包.相反，安装一个分叉版本的包.

You should never edit an installed package. Instead, install a forked version of package.

如果你需要经常编辑代码，不要通过pip install something安装包，并在'.../site_packages/...'中编辑代码

If you need to edit the code frequently, DO NOT install the package via pip install something and edit the code in '.../site_packages/...'

相反，将源代码放在开发目录下，并使用

Instead, put the source code under a development directory, and install it with

python setup.py develop
# or
pip install -e path/to/SomePackage
# Or use a vcs at the first place
$ pip install -e git+https://github.com/lakshmivyas/hyde.git#egg=hyde

将您的更改放在版本控制系统中，并告诉 pip 显式安装它.

Put your changes in a version control system, and tell pip to install it explicitly.
