为pip安装缓存远程存储库 [英] Caching remote repository for pip installs

问题描述

在我的pi需求文件中，我需要各种回购的特定提交，即：

  git + http：// github .com / frankban / django-endless-pagination.git @ 725bde91db＃egg = django-endless-pagination 
  

我遇到的问题是，它明显需要点子才能在每次安装时重新克隆repo，而完全忽略默认的下载缓存。

有什么方法吗？要求这个回购缓存在本地？
或者，或者，最好的解决方案是将其封装并保持本地可用？

解决方案

您可以做两件事：使用可编辑安装，或者使用 -e 开关将导致> pip 将资源库克隆到virtualenv的 src 子目录中;您可以在每次重新安装时重新使用该副本：

  pip install -e -r requirements.txt 
  

然后Pip每次重新运行命令时重新使用现有的源代码（从git更新，而不是或者，因为安装使用了实际的工作目录，所以你可以在 src /目录中使用 git pull django-endless-pagination 代替。

您可以将pip安装的结果缓存为 Python Wheel ：

  pip wheel  -  wheel-dir = / tmp / wheelhouse -r requirements.txt 
  

这将安装所有要求并为 / tmp / wheelhouse 中的每个要求创建轮子。然后，您可以重新使用控制台进行后续安装：

  pip install --use-wheel --no-index  - find-links = / tmp / wheelhouse -r requirements.txt 
  

车轮不会从但是。

In my pi requirements file, I require specific commits of various repos, ie:

git+http://github.com/frankban/django-endless-pagination.git@725bde91db#egg=django-endless-pagination

The problem I'm having with this is that it apparently requires pip to clone the repo anew for every install, ignoring the default download cache entirely.

Are there any ways to require this repo to be cached locally? Or, alternately, what is the best solution to package this up and keep the package locally available?

解决方案

You can do two things: use an editable install, or cache the result of the install as a wheel.

Using the -e switch causes pip to clone the repository into the src subdirectory of your virtualenv; you can then reuse that copy each time you want to re-install:

pip install -e -r requirements.txt

Pip then just re-uses the existing source each time you re-run the command (updating from git rather than pulling in a completely new copy of the repo), or, since the installation uses the actual working directory, you can just use git pull in src/django-endless-pagination instead.

You can cache the result of the pip install as a Python Wheel:

pip wheel --wheel-dir=/tmp/wheelhouse -r requirements.txt

This installs all the requirements and creates wheels for each in /tmp/wheelhouse. You can then re-use the wheelhouse for subsequent installs:

pip install --use-wheel --no-index --find-links=/tmp/wheelhouse -r requirements.txt

The wheels won't be updated from the repository however.
