清理 conda 缓存的安全方式

conda 缓存一般在 pkgs 文件夹下，虽说可以直接删除，但是这样会造成不好的影响，例如不能使用已经缓存的下载包，不同环境包不能软连接，推荐这种方式 conda clean --all

usage: conda-script.py clean [-h] [-a] [-i] [-p] [-t] [-f] [-c TEMPFILES [TEMPFILES ...]] [-d] [--json] [-q] [-v] [-y]

Remove unused packages and caches.

Options:

optional arguments:
  -h, --help            Show this help message and exit.

Removal Targets:
  -a, --all             Remove index cache, lock files, unused cache packages, and tarballs.
  -i, --index-cache     Remove index cache.
  -p, --packages        Remove unused packages from writable package caches. WARNING: This does not check for packages installed using symlinks back to the package cache.
  -t, --tarballs        Remove cached package tarballs.
  -f, --force-pkgs-dirs
                        Remove *all* writable package caches. This option is not included with the --all flag. WARNING: This will break environments with packages installed using symlinks back to the package cache.  
  -c TEMPFILES [TEMPFILES ...], --tempfiles TEMPFILES [TEMPFILES ...]
                        Remove temporary files that could not be deleted earlier due to being in-use. Argument is path(s) to prefix(es) where files should be found and removed.

Output, Prompt, and Flow Control Options:
  -d, --dry-run         Only display what would have been done.
  --json                Report all output as json. Suitable for using conda programmatically.
  -q, --quiet           Do not display progress bar.
  -v, --verbose         Can be used multiple times. Once for INFO, twice for DEBUG, three times for TRACE.
  -y, --yes             Do not ask for confirmation.
