问题描述

我喜欢编辑安装有 pip 的python模块。但是,我不知道如何在升级模块时避免本地更新和原始更新之间的冲突。



例如,

  $ pip install some_module 
$ vim〜/.../ some_module / something.py#更新文件
$ pip install --upgrade some_module

由于本地资源库和原始资源库之间存在冲突,应该会发生一些麻烦。 (原始repo在github上的假设是OK的)



我猜想其中一个替代方法是在github上分发版本库, pip install git +< repo_url> ,但我没有信心。



避免这种麻烦的好方法是什么?

解决方案

你不应该编辑模块的核心文件,如果你需要修改它,你应该扩展(继承)它并覆盖功能和添加你自己的函数,这样你的代码与repo的代码是分开的,不会被更新或升级覆盖。

你也可以使用虚拟环境,一个虚拟环境是一个孤立的Python安装/环境,它可以很容易地管理依赖和不同版本的库/ Python的版本



这应该让你开始

I like to edit python modules installed with pip. But, I do not know good way to avoid conflicts between local update and original one when upgrade a module.

For example,

$ pip install some_module
$ vim ~/.../some_module/something.py # update the file
$ pip install --upgrade some_module

It should occurs some trouble because of conflicts between local and original repository. (The assumption that original repo is on github is OK)

I guess One of alternatives is forking repository on github and pip install git+<repo_url>, but I'm not have confident.

What is good way to avoid this trouble?

解决方案

You should not be editing the core files of a module, if you need to modify it you should be extending (subclassing) it and over-riding the functionality and adding your own functions, that way your code is separate from the repo's code and won't be over-written by an update or upgrade

You could also Use a virtual environment, a virtual environment is an isolated python installation/environment, it makes it easy to manage dependencies and different version of libraries/ version of python

this should get you started
