我正在尝试为Rails 3.1创建自定义生成器。而我写这篇:为什么'bundle install'在Rails生成器中失败?
module SomeGem
module Generators
class InstallGenerator < Rails::Generators::Base
source_root File.expand_path('../templates', __FILE__)
desc "This adds devise"
def install
gem "devise"
run "bundle install"
end
end
end
end
但是当我运行这个生成器(轨道摹somegem:安装,在新鲜生成的Rails应用程序),我已经收到此错误:
gemfile devise
run bundle install
Could not find gem 'devise (>= 0)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.
我发生器增加正确设计Gemfile,但在从生成器运行“bundle install”命令时失败。当我从控制台运行“捆绑安装”时,它会安装所有gem而不会出现任何错误。
这是怎么发生的?
这是我的Gemfile我跑后 '轨道摹somegem:安装'(我删除了自上市注释):
source 'http://rubygems.org'
source 'http://gemcutter.org'
source "http://gems.github.com"
gem 'rails', '3.1.0'
gem 'mysql2'
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
gem 'jquery-rails'
group :test do
# Pretty printed test output
gem 'turn', :require => false
end
gem 'therubyracer'
gem "devise"
请确保您在运行'bundle install'命令时连接到网络 –
