我正在尝试初始化rails应用程序，我遇到了一些问题。运行时：rails new . -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
我遇到了这个问题：
Could not find gem 'quiet_assets (>= 0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
当我尝试运行bundle install时，它给了我这个错误：
An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling.
当我运行该命令时，我得到：
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
有什么想法吗？我有下面的完整输出（问题从哪里开始，作曲家试图安装宝石束）：
composer Installing gems. This will take a while.

最有可能的是，你没有安装mysql。 gem只是Ruby绑定 - 它使用了底层的mysql库。先安装它。如果您已安装brew：
brew install mysql
如果不是，install it，安装大量软件包将非常有用。
答案 1 :(得分：0)
我在使用Rails 3.0应用时遇到了类似的问题。确保测试和开发组中都包含mysql / sqlite gem。
