Anaconda Clean命令

conda 安装的包都在目录Anaconda/pkgs下。随着使用，conda 安装的包也越来越多；有时候会出现以下不好的情况：

有些包安装之后，从来没有使用过； 一些安装包的tar包也保留在了计算机中； 由于依赖或者环境等原因，某些包的不同版本重复安装。 上面的这些情况使得anaconda显得更加冗余，并且浪费储存；对于这些情况可以使用conda clean 净化Anaconda。

Conda clean使用

删除从不使用的包

$ conda clean --packages

删除tar包

$ conda clean --tarballs

删除索引缓存、锁定文件、未使用过的包和tar包

$ conda clean -a

清楚索引缓存

$ conda clean -i

应用情况

今天我在使用conda安装opencv的时候一直报unexpected error的错误，经过一番尝试发现使用

conda clean -i

可以很好地解决该问题。
