Step 1-install rvm

What rvm is doing is not explained here, and you will understand it later.

$Bash <(curl-s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

After waiting for a while, you can successfully install rvm. At this time, there will be a prompt that you wantCodePut in ~ /. Bashrc or ~ /. Bash_profile (MAC.

# Note thatChange/users/Jason to your home path, such as/home/lgn21st.

[[-S"/Users/Jason/. Rvm/scripts/rvm "] & source"/Users/Jason/. Rvm/scripts/rvm"

Then reload the. bashrc or. bash_profile file.

$Source ~ /. Bash_profile

Test whether the installation is correct

$Rvm-V

Rvm 1.9.2 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]

Step 2-Use rvm to install the ruby Environment

$Rvm PKG install Readline

$Rvm install 1.9.2-with-Readline-Dir = $ rvm_path/usr

You can also install version 1.8.7 or 1.9.3. You only need to change the later version.

We will also continue to wait for a long download. After the compilation process is completed, Ruby and Ruby gems will be installed.

Step 3-set the ruby version

After the rvm is installed, You need to execute the following command to set the ruby of the specified version to the default version of the system.

$ Rvm 1.9.2-Default

You can also use other versions, provided that you have installed the version with rvm install.

At this time, you can test whether it is correct.

$Gem source-r http://rubygems.org/

$Gem source-A http://ruby.taobao.org

Step 4-install the rails Environment

$Gem install bundler rails

Then test whether the installation is correct.
