Error running '__rvm_make install'

问题:

I'm new to programming trying to add Ruby 2.2 using RVM and receiving the below error. I've run rvm get stable and tried reinstalling, but getting the same error.

$ rvm reinstall ruby-2.2.0

Try to update your rvm using command

rvm get head

Then try again. Hopefully it should work.
