Is there any way to update some package install cache?

[Gwill]

I got a error when I install a package because the bad network, it is downloading part of package, so the md5 check return error.

and then, it always return error when I install this package, because the half bad package was caching.

so, Is there any way to update some package install cache?

You'll just need to delete the cache and start over. The underlying issue is located psf/cachecontrol#83.

but, I was cache many packages, It is sad to rebuild ~/.cache

Closing this, it appears that the underlying issue has been fixed and pip will no longer attempt to cache partial downloads.
