Update Ruby on Mac

Since you are ready to use bootstrap in your project, you will be prompted for a ruby version at 1.9.2 during the installation of Bootstrap, while the Ruby version that is currently in use is the 1.8.7 that comes with the Mac system. So you need to upgrade Ruby. In this case, Ruby is upgraded using RVM, which is as follows:

1, installation RVM

Rvm:ruby version Manager,ruby release manager, including Ruby version management and GEM Library Management (Gemset)

get. Rvm.io | Bash-s Stable  

Wait a while before you can successfully install the RVM.

    $ source ~/. BASHRC      ~/.bash_profile  

Test whether the installation is normal

Rvm-v  

2. Upgrade Ruby with RVM

    #查看当前ruby版本       -v      1.8.  7      #列出已知的ruby版本      $ RVM list known      1.9.  3      1.9.  3  

After the installation is complete ruby-v see if the installation is successful.
