How to update rvm behind a proxy server?

I am behind a proxy server and thus I cannot update rvm with rvm update.

I have a CNTLM proxy locally running and all my http connections go succesfully through it.

Though, rvm update doesn't work, probably because it is using the git p开发者_开发技巧rotocol.

Does anyone know how to solve this problem without having to reinstall rvm?

This question applied to some quite old version of rvm. I had to remove rvm:

rvm implode

and then I reinstalled it and it worked fine.
