Really, I don't know what happened. Excuse me if this question is so NOOB, but I can't find the solution for this problem.
-bash: rvm: command not found
I tried this
curl -L https://get.rvm.io | bash -s -- --version latest
but still nothing I need to see the ruby version for use the simplecov because it not works with older version from 1.9
It might because the terminal not having rvm shell configuration loaded.
Try following from your terminal:
$ source ~/.rvm/scripts/rvm
then
$ type rvm | head -n 1
If the output is:
rvm is a function
You may need to add "source ~/.rvm/scripts/rvm" to your ~/.bash_profile file
you need to read all the texts that are displayed when you install RVM:
rm -rf ~/.rvm
curl -L https://get.rvm.io | bash -s stable
after you run sudo curl -L https://get.rvm.io | bash -s stable --ruby
you need to close the terminal ,then open again!
This worked for me:
rm -rf ~/.rvm
curl -L https://get.rvm.io | bash -s stable
source /etc/profile worked for me.
Close and restart terminal after installing RVM — gets me EVERY TIME.
For a long-term solution, you should add this to your ~/.profile file:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
to simply load rvm into a single terminal, use
source "$HOME/.rvm/scripts/rvm"
supposedly this call is more cross-platform:
. "$HOME/.rvm/scripts/rvm"
To start using RVM, you'll need to enter source /Users/yourusername/.rvm/scripts/rvm into your terminal (of course, insert your real username in place of yourusername).
