alex@ubuntu:~/Documents/ruby_projects/my_project$ rvm --create --rvmrc 1.9.3@my_project
这个给了我
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.
为什么我无法以这种方式创建 rvmrc?
