PyPI（以及其他 包索引）的镜像或缓存可以用来加速本地包的安装， 支持离线工作，处理公司防火墙问题或应对网络不稳定。

这一领域有多种选择类型：

1. 包索引的本地/托管缓存。

2. 包索引的本地/托管镜像。镜像是包索引的（完整或部分）副本，可以用来替代原始的索引。

3. 具有回退到公共包索引功能的私人包索引（例如，用于缓解依赖混淆攻击），也称为代理。

Mirroring or caching of PyPI (and other package indexes) can be used to speed up local package installation, allow offline work, handle corporate firewalls or just plain Internet flakiness.

There are multiple classes of options in this area:

1. local/hosted caching of package indexes.

2. local/hosted mirroring of a package index. A mirror is a (whole or partial) copy of a package index, which can be used in place of the original index.

3. private package index with fall-through to public package indexes (for example, to mitigate dependency confusion attacks), also known as a proxy.

使用 pip 缓存

Caching with pip

中文

pip 提供了多种加速安装的方式，通过使用本地缓存的 包 副本：

1. 快速和本地安装，通过下载项目所需的所有依赖项，然后让 pip 使用这些下载的文件，而不是去 PyPI。

2. 上述方法的变体，通过使用 python3 -m pip wheel 预构建安装文件：

   python3 -m pip wheel --wheel-dir=/tmp/wheelhouse SomeProject
   python3 -m pip install --no-index --find-links=/tmp/wheelhouse SomeProject
   

英文

pip provides a number of facilities for speeding up installation by using local cached copies of packages:

1. Fast & local installs by downloading all the requirements for a project and then pointing pip at those downloaded files instead of going to PyPI.

2. A variation on the above which pre-builds the installation files for

the requirements using python3 -m pip wheel:

python3 -m pip wheel --wheel-dir=/tmp/wheelhouse SomeProject
python3 -m pip install --no-index --find-links=/tmp/wheelhouse SomeProject
