如何使用Fedora Ruby堆栈设置一个简单的Ruby on Rails应用程序

Question

如何使用yum安装的软件包设置Rails应用程序？

Answer 1

Just don't do that. I can't imagine any valid reason not to use some kind of Ruby version management software -Maybe that's my ignorance if so, please enlighten me-.

If you decide to use RVM -which is perfectly documented, supported, updated bla bla bla..-

Just install it without any pain using this command:

$ \curl -sSL https://get.rvm.io | bash

After installation completed, you're free to install as much as Ruby versions to your system without any conflict concerns... Installing a Ruby version is as easy as this (No dependency worries!!):

$ rvm install 2.1

After this step is done too, you can make it default:

$ rvm use 2.1 --default

And from now on, using gemset s you have the power of freedom!

If you don't want to create any specific gemsets, you are free to use default one without setting anything. To create a Rails app?

$ gem install rails
$ rails new myApp

Cheers. But wait...

Please... Just don't use stack Rubies.

Update: rbenv is another great option!

如果不包括sudo yum install ruby​​-devel ，则会收到错误消息，找不到ruby.h。
