I’m trying to install Rails using Gem and did the following from the terminal:
sudo apt-get install ruby-full build-essential
sudo apt-get install rubygems
export PATH=/var/lib/gems/1.8/bin:$PATH
gem install rails
Then I get the following message:
ERROR: While executing gem … (Errno:EACCES)
Permission denied – /var/lib/gems
I’ve followed the instruction from Ubuntu Help Guide & I’m using Oracle VM VirtualBox to run Ubuntu under Windows 7 and have RubyGems v1.8.15.
You need to prefix the
gemcommand withsudobecause/var/lib/gemsis owned byroot. You could also take a look at RVM which allows really easy installation and management of gems and Ruby versions. Best part, it’s all in your home dir!EDIT: per @AndrewMarshall’s comment bellow, rbenv is an alternative to RVM.
