Ruby on Rails安裝 - Ubuntu 15

Question

我想在Ubuntu 15（64位）中安裝RoR。我已經完成了大部分安裝過程，比如安裝rvm，ruby，mysql服務器，創建gemset。

rails new first_app 
rvm gemset list 
rvm gemset use rails3.2.13 
rails new first_app 
cd first_app/ 
bundle install 

上面的逗號成功執行。

Ruby version 2.2.1 
Rails version 3.2.13 

當我嘗試啓動我的服務器，我收到錯誤，如下面

rails s 
/home/ela/.rvm/gems/ruby-2.2.1@rails3.2.13/gems/activesupport-3.2.13/lib/active_support/values/time_zone.rb:270: warning: circular argument reference - now

    from script/rails:6:in `<main>' 

我的寶石文件::

source 'https://rubygems.org' 

gem 'rails', '3.2.13' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

gem 'mysql2' 


# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

爲 'uglifier' 寶石也因此同樣的錯誤我刪除了這兩個寶石。然後我在mysql適配器中出錯。

有人請幫助我。提前致謝。

Answer 1

安裝的NodeJS

sudo apt-get install nodejs 

然後用

bundle install
