Ruby Gems Returns "Command Not Found"

Ruby Gems returns command not found

Your $PATH variable needs to include the exact path to your Ruby's bin directory. Adding a directory to the PATH does not include it's subfolders. Try adding the bin directory via:

export PATH=$PATH:/home/adam/.gem/ruby/1.8/bin

or if you installed the gem using sudo:

export PATH=$PATH:/usr/lib/ruby/gems/1.8/bin

You might want to add this to your .bashrc file, so that you don't have to set this manually every time your open up a new bash.

Gem installed but 'command not found'

So you're working with rbenv. According to its README, you should run rbenv rehash after installing any gems that have an executable command. Also, run it anytime you install a new Ruby version.

Gem Command not found

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

Ruby works, but gem command not found - via SSH

RubyGems is in standard installation since 1.9.x so you need to install RubyGems or use RVM or rbenv to use newer version.

Rails command not available after installing with gemfile

So, I was running rbenv rehash and setting the environment variable. However, the new env variables were not available until after a restart. Using the full path to /.rbenv/shims/rake solved the problem.

Can't execute installed gem `erb2slim` using rbenv

Please try the alternative provided by html2slim:

https://rubygems.org/gems/html2slim/versions/0.2.0

This should provide a erb2slim executable as well as an html2slim executable

Command 'rbenv' not found, but can be installed with

Well in the github repo I can't seem to find the method/script you are using to install.

just use the complete manual approach as specified on the website as of today.

remove every rbenv related line first from your ~/.bashrc, and rm -rf ~/.rbenv then just copy-paste the below lines.

git clone https://github.com/rbenv/rbenv.git ~/.rbenv --depth=1 #shallow clone cuz ig u just want to use it
cd ~/.rbenv && src/configure && make -C src
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

should work just fine, + you get the additional benefit of getting the latest version. whenever you wish to update just cd ~/.rbenv && git pull

comment if still issues.
