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

问题描述

我通过pip install something安装了一些软件包.我想编辑包something的源代码.它在哪里(在ubuntu 12.04上)，并且每次我编辑源代码并运行它时如何重新加载它?

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?

当前，我正在编辑源代码，然后一次又一次地运行python setup.py，事实证明这很麻烦.

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

永远不要编辑已安装的软件包.而是安装分叉版本的软件包.

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

如果您需要经常编辑代码，请不要通过pip install something安装软件包，也不要在'.../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

将所做的更改放入版本控制系统中，并告诉pip明确安装它.

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