Gem Command not found

Ruby Problem Overview

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

Ruby Solutions

Solution 1 - Ruby

Try the following:

sudo apt-get install rubygems

Solution 2 - Ruby

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

Solution 3 - Ruby

The following command installs ruby gem for ubuntu:

apt-get install libgemplugin-ruby

I did it after ruby was installed.

Solution 4 - Ruby

Installing this package allows you to use gem command on Debian 8:

apt-get install rubygems-integration

To install a gem package you might also need:

apt-get install ruby ruby-dev

Solution 5 - Ruby

On Debian, Ubuntu or Linux Mint:

$ sudo apt-get install rubygems ruby-dev

On CentOS, Fedora or RHEL:

$ sudo yum install rubygems ruby-devel

Solution 6 - Ruby

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

Solution 7 - Ruby

The following command may help you

> sudo apt-get install ruby

Solution 8 - Ruby

On CentOS 7 you can do:

> yum -y install rubygems-devel

That worked for me.

Solution 9 - Ruby

On Ubuntu 14.04,

apt-get install ruby ruby-dev

this will install gem for you.

Solution 10 - Ruby

I had the same problem. What I did was:

sudo apt-get update

And then reinstall ruby-full

sudo apt-get install ruby-full

Solution 11 - Ruby

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.

Solution 12 - Ruby

check that rvm is a function type rvm | head -1

Solution 13 - Ruby

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

dpkg -L gem

that should help you troubleshoot.

Solution 14 - Ruby

try

$ /usr/bin/pd-gem

$ pd-gem

Solution 15 - Ruby

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).
