Installing Ruby on Ubuntu
As seen on RVM
Go to the terminal in Ubuntu.
On the Terminal go to the Menu/Edit/Profile Preferences/Title
and Command.
Check Run command as a login shell
.
Close the Terminal and start a new one.
Add the public key from RVM
$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
Then run this command to install RVM
$ \curl -sSL https://get.rvm.io | bash -s stable
If the result says “GPG signature verification failed”. It says to “try to install GPG v2 and then fetch the public key”:
$ gpg2 --recv-keys string-letters-numbers
Above copy/paste the corresponding string that is shown on your terminal.
If that still doesn’t work it will say:
gpg: keyserver receive failed: No keyserver available
The next troubleshooting is to enter this:
$ command curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
If that works it should say something like:
gpg: starting migration...
gpg: porting secret keys
gpg: migration succeeded
gpg: key...public key...
gpg: Total number processed: 1
gpg: ....imported: 1
Then run the command again to install RVM:
$ \curl -sSL https://get.rvm.io | bash -s stable
If it works it should say something like:
Installing RVM to /home...
Adding RVM PATH line to ...
Adding rvm loading line to ...
* To start using RVM you need...
Close the terminal and open it again.
$ source ~/.rvm/scripts/rvm
$ type rvm | head -n 1
This should now say rvm is a function
Install Ruby. As of this writing the stable version was 2.4.2
$ rvm install 2.4.2
$ rvm use 2.4.2 --default
Use Gemsets
To work on different projects create a Gemset.
$ rvm use 2.4.2@name-of-project --create
List gemsets with:
$ rvm gemset list
Switch gemsets with:
$ rvm gemset use name-of-gemset
