Ruby Environment installation under IOS Mac system

A series of questions elicited by Easyios: the previous Cocoapods installation and use tutorial in the reprint explains why you should use Cocoapods, but to install cocoapods requires a ruby environment, Installing the ruby environment first requires the installation of Xcode (because of the Xcode development tool, he helps us install the development packages needed for the UNIX environment) and then needs to install homebrew. Next you need to install RVM finally install ruby environment

Here's the order of installing cocoapots:

xcode->homebrew->rvm->ruby->cocoapats;

This article explains how to install the part of Ruby, on the installation of Ruby and then install cocoapats parts Please see my previous article reproduced cocoapats;

The following is said above the tall on the English letter noun is why (in fact, I do not understand, are Baidu out, my google these days are not used):

Xcode

Xcode doesn't have to say.

Homebrew

Homebrew is a package manager that installs some UNIX tools (such as wget) that are not available on the Mac (wget I don't know what it is), but as a rookie, just know it's like a window's 350 software manager to install some software.

Installation of RVM

?

1	$ curl -L https://get.rvm.io | bash -s stable

You may be asked for the sudo administrator password and automatically install the dependency package through homebrew, waiting for a period of time before you can successfully install the RVM. Then, load into the RVM environment (new open termal will not do so, will automatically reload)

?

1	$ source ~/.rvm/scripts/rvm

Check to see if the installation is correct

?

12	$ rvm -vrvm 1.22.17(stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]</[email protected]>

installation Ruby

?

1	$ rvm install 2.0.0

Also continue to wait for a lengthy download, the compilation process, after completion, Ruby, Ruby Gems is installed.

Management Ruby version

After the RVM is installed, you need to execute the following command to set the specified version of Ruby to the system default version

?

1	$ rvm 2.0.0--default

Also, you can use a different version number if you have a RVM install installed that version

This time you can test whether it is correct
