Gem Command not found

问题:

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

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

回答2:

Try the following:

sudo apt-get install rubygems

The following command installs ruby gem for ubuntu:

apt-get install libgemplugin-ruby

I did it after ruby was installed.

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

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

回答6:

The following command may help you

sudo apt-get install ruby

回答7:

On Debian, Ubuntu or Linux Mint:

$ sudo apt-get install rubygems ruby-dev

On CentOS, Fedora or RHEL:

$ sudo yum install rubygems ruby-devel

回答8:

On CentOS 7 you can do:

yum -y install rubygems-devel

That worked for me.

回答9:

On Ubuntu 14.04,

apt-get install ruby ruby-dev

this will install gem for you.

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.

回答11:

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

回答12:

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

dpkg -L gem

that should help you troubleshoot.

回答13:

try

$ /usr/bin/pd-gem

or

$ pd-gem
