RVM on debian and rails 3

I'm following https://github.com/diaspora/diaspora/wiki/Installing-on-Debian and try开发者_Go百科ing to get RVM installed on debian. Executing

bash < <(curl -s https://rvm.io/install/rvm)

gives me nothing, it does not result in anything. I have curl installed but the command doesn't generate any output.

You can just download https://rvm.io/install/rvm via browser and then execute bash ./rvm . The command you entered actually executes the same.

EDIT: the new way:

curl -L https://get.rvm.io -o rvm-installer
chmod +x rvm-installer
./rvm-installer
rm -f rvm-installer

Which is equivalent to:

curl -L https://get.rvm.io | bash

The former command was using -s without -S which was hiding errors from curl.
