我试图在Ubuntu 15(64位)中安装RoR.我已经完成了大部分安装过程,比如安装rvm,ruby,mysql服务器,创建gemset.
rails new first_app rvm gemset list rvm gemset use rails3.2.13 rails new first_app cd first_app/ bundle install
上面的逗号已成功执行.
Ruby version 2.2.1 Rails version 3.2.13
当我尝试启动我的服务器时,我收到如下错误

我的宝石文件::
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'
"uglifier"gem的错误也是如此,所以我删除了那两颗宝石.然后我在mysql适配器中收到错误.
