我正在尝试使用 codeship 设置持续集成。我们的项目是一个带有 Angular 应用程序的 Rails API，目前它位于public目录中。为了工作，grunt 需要找到 compass 可执行文件。
我会说设置命令应该是：
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
和测试管道：
bundle exec rspec
cd public && grunt test
但是，似乎 codeship 不喜欢gem install compassline 并且它抱怨：
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

Use --force to continue.
它给了我一个我不确定理解的提示：
Please make sure the gem wasn't yanked from http://www.rubygems.org
但是，如果我删除gem install compass行，而是添加compass到我的 Rails 应用程序Gemfile，它就可以工作。但是我真的觉得在我的 Gemfile 中添加指南针很难看。它与它无关。我的 Rails 应用程序是一个 REST API，所以它不想知道任何关于 compass、css 或类似的东西。
谢谢。
