Editor to share with you how to install rails, I hope you will learn something after reading this article, let's discuss it together!

Began to learn rails, the first step is to learn how to build a good environment, I use the mac-pro,Mountain Lion version.

1. Install homebrew: (homebrew is a package management tool under mac system, similar to rpm, etc.)

Ruby-e "$(curl-fsSL https://raw.github.com/mxcl/homebrew/go)"

2. Install rbenv with your homebrew: (rbenv is used to manage ruby versions, similar to rvm)

Brew install rbenv

3. Create a file for your rails project

Mkdir ~ / Learning/rails

4. Create .rubyversion file, and add the version you want to install

Vim .rubyversion

5. Check your local ruby version with:

Rbenv local

6. Install your ruby:

Rbenv install 2.0.0-p247

Since you are installing the latest 2.0.0-p247, you may encounter some problems. If you use mountain lions like me, you need update your OpenSSL and ruby build with:

Brew update & & brew install openssl

Brew upgrade ruby-build

After that, you can continue with the operation in step6

7. Install your rails with gem:

Gem install rails

Of course, if the network is shabby, you can use other rubygems images, such as Taobao (gem downloads relevant bao packages from https://rubygems.org/ by default)

Gem sources-- remove https://rubygems.org/

Gem sources-a http://ruby.taobao.org/

After that, you can view the result of the modification through gem sources-l

8. Start your rails life

Rails *

Of course, if you still can't use rails command, you need to use bundle to operate. Bunlder is a class library based on ruby, but it is also a kind of gem, but this gem can be used to manage other gem. Moreover, when you use bundle exec rails, it will only operate in the current directory, will not affect anywhere else, and is relatively safer.

Brew install bundler

Bundle install

Bundle exec rails *
