目录

共享软件包缓存的好处是，一旦用户已经下载了软件包的特定版本，它将不会再次下载并存储在单独的缓存中。这节省了磁盘使用量并加快了安装速度，因为它不需要再次下载软件包。

通过查看了解到我现在已经配置了共享软件包的缓存目录（package cache）：/opt/miniconda/pkgs 和 /Users/junjian/.conda/pkgs，根据顺序优先存放在 /opt/miniconda/pkgs 目录中。

共享软件包缓存设置

编辑 ~/.condarc，指定共享缓存目录的完整路径：

pkgs_dirs:
    - /path/to/shared_directory

配置完成后，可以通过运行 conda info 来查看配置是否生效。

pip

查看缓存目录

pip cache dir
/Users/junjian/Library/Caches/pip

查看缓存信息

pip cache info

Package index page cache location: /Users/junjian/Library/Caches/pip/http
Package index page cache size: 1958.8 MB
Number of HTTP files: 1153
Locally built wheels location: /Users/junjian/Library/Caches/pip/wheels
Locally built wheels size: 33.1 MB
Number of locally built wheels: 47

缓存设置

查看 pip 的配置文件

pip config list -v

For variant 'global', will try loading '/Library/Application Support/pip/pip.conf'
For variant 'user', will try loading '/Users/junjian/.pip/pip.conf'
For variant 'user', will try loading '/Users/junjian/.config/pip/pip.conf'
For variant 'site', will try loading '/opt/miniconda/pip.conf'

选择一个在不同虚拟环境中都会出现的文件，用于配置共享软件包缓存目录

mkdir /Users/junjian/.config/pip
vim /Users/junjian/.config/pip/pip.conf

[global]
cache-dir=/Users/junjian/.cache/pip

配置完成后，可以通过运行 pip cache dir 来查看配置是否生效。

可以运行 pip cache -h 了解更多的功能。

我的缓存目录

Conda - /opt/miniconda/pkgs

pip - /Users/junjian/Library/Caches/pip
