Notes for installing Ruby in Ubuntu

Here, we will talk about installing Ruby through apt-get, which will eliminate the need for self-compiling.

First, you must install both Ruby and ruby-dev when installing Ruby. The current version is 1.8, so you should execute the following command Java code

1. Sudo apt-Get install ruby1.8 ruby1.8-dev rubygems

sudo apt-get install ruby1.8 ruby1.8-dev rubygems 

This is because many plug-ins or gems depend on the stuff in Dev. For example, Ferret will use something called mkmf, which is included in Dev.

You can install rails using gem or apt-get, but we recommend the former because the version is definitely the latest. For example, if rails is not 1.2 In the source I use, it is not good to use apt-Get.

The last step is to find out where these things are installed. You can run the find command Java code in the root directory.

1. Sudo find-INAME * Ruby *> result.txt

sudo find -iname *ruby* >> result.txt 

The following is the running result Java code on my computer.
