在Linux Mint中开始Ruby on Rails

Question

This may sound very basic to many of you. I have just started a Ruby on Rails tutorial in Linux. I'm very new to the Linux OS. I have installed a rvm. But I am unable to install Rails. It's saying "cant load such file --zlib". And I can see two source files for Ruby. Not sure if I have two Ruby installed.

Answer 1

Just take a note that you have selected the correct build system:

"Tools -> Build System -> Ruby"

Then press CTRL+B . This should work.

Answer 2

您可以使用ctrl + b崇高地执行.rb文件。

Answer 3

It seems you are a bit confused about how Ruby on Rails work. Sumblime can run your ruby code but not on Rails stack. My suggestion it's to work always with an open terminal on the directory of your rails application. Let's assume you created a new rails project as

rails new helloWorld

The rails generetor will create a subfolder helloWorld.This will be your working directory in the terminal. So you have to do:

cd helloWorld

and then

rails s

It will run your rails application on an embedded server on localhost:3000 by default.

Answer 4

What method did you use to install ruby?

If you compiled from source you may need to do

   sudo apt-get install libssl-dev

And then recompile ruby

Otherwise, you may not have the most recent version of Rubygems

Try: go to https://github.com/rubygems/rubygems/releases/tag/v2.2.3

download rubygems-update-2.2.3.gem

call the directory where the file was dl'ed, then

   gem install rubygems-update-2.2.3.gem

   update_rubygems --no-ri --no-rdoc

   rubygems --version #Should show 2.2.3

   gem install rails
