我将尝试与Codeship配合完成持续集成。我们的项目是一个Rails API和一个Angular应用程序，目前位于public目录中。为了使其正常工作，grunt需要找到compass可执行文件。
我认为设置命令应该是:
rvm use 2.1.3 --install
bundle install
export RAILS_ENV=test
bundle exec rake db:schema:load
bundle exec rake db:migrate
bundle exec rake db:test:prepare
# We need compass in frontend
gem install compass
nvm install 0.10.25
nvm use 0.10.25
npm install
npm install -g grunt-cli
测试流程：
bundle exec rspec
cd public && grunt test
然而，似乎 Codeship 不喜欢 gem install compass 这行代码，并报以下错误：
Running "concurrent:test" (concurrent) task Warning: /home/rof/.rvm/gems/ruby-2.1.3/gems/bundler-1.9.4/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find rake-10.4.2 in any of the sources

这给了我一个提示，但我不确定是否理解：
Please make sure the gem wasn't yanked from http://www.rubygems.org
然而，如果我删除
gem install compass这一行，并且将compass添加到我的Rails应用程序的Gemfile中，它就可以工作了。但是我真的对将compass添加到我的Gemfile中感到丑陋和不好。它与此无关。我的Rails应用程序是一个REST API，因此不想知道任何有关compass、css或类似内容的信息。谢谢。
