Gem Command not found

I have installed gem on Ubuntu 10.10 32 bit with 

apt-get install gem -y

But when I try to run

gem install something.gem

I get the error of the command not being found.

bash: gem: command not found

I installed gem, is there any reason it is saying it can't find the command?

These files were install by gem package

On Centos 8:

eventually, download the file of the application:

wget https://rubygems.org/downloads/asciidoctor-2.0.16.gem

then execute:

yum install -y rubygems ruby-devel
gem install asciidoctor

More: I tried positively also in a container (using the appropriate RUN and COPY statements before the commands).

I had the same problem. What I did was:

sudo apt-get update

And then reinstall ruby-full

sudo apt-get install ruby-full

On CentOS 7 you can do:

yum -y install rubygems-devel

That worked for me.

I know this is kind of late for a response. But I did run into this error and I found a solution here: https://rvm.io/integration/gnome-terminal

You just have to enable 'Run command as login shell' under the terminal preferences.

FWIW, the equivalent package for RHEL/Fedora/CentOS/etc and SuSE/OpenSuSE appears to be called 'rubygems'.

Are you wanting ruby gems? If so, you need to install libgemplugin-ruby and then the ruby 'gem' program will be in your path:

aptitude install libgemplugin-ruby

The following command will give you the list of files that the gem package installed:

dpkg -L gem

that should help you troubleshoot.
