方法一：让Anaconda自行决定清理

执行命令

conda clean -p

我的Anaconda安装在D盘，具体位置如下。你的应该也能找到对应的位置

D:\*****\**\Anaconda3\pkgs

(base) C:\Users\Liu_J>conda clean -p
WARNING: C:\Users\***\.conda\pkgs does not exist
WARNING: C:\Users\***\AppData\Local\conda\conda\pkgs does not exist
Cache location: D:\ProgramData\Anaconda3\pkgs
Will remove the following packages:

方法二：安全的删除pkgs全部的包

这个主要是清理缓存包，不会直接影响已经创建的虚拟环境

命令如下：

conda clean --all

(base) C:\Us***\****>conda clean --all
Cache location: D:\ProgramData\Anaconda3\pkgs
Will remove the following tarballs:D:\*****\**\Anaconda3\pkgs
