我在将我的应用程序配置为用户 wercker 时遇到问题。我的 wercker.yml 看起来像这样：

box: ruby
services:
  - postgres
build:
    steps:
        - script:
            name: Nokogiri fix
            code: bundle config build.nokogiri --use-system-libraries
        - bundle-install
        - rails-database-yml
        - script:
            name: Set up db
            code: bundle exec rake db:schema:load RAILS_ENV=test
        - script:
            name: rspec
            code: bundle exec rspec

当我运行构建它失败并出现以下错误：

我认为我需要在 wercker 上安装 nodejs，但问题是我该怎么做？

正如对问题的评论所暗示的，您需要安装一个 javascript 运行时。

你有几个选择：

  1. 添加gem 'therubyracer'到您的 Gemfile。
  2. 通过 apt-get、brew 等安装 nodejs。

我会选择选项 2，以免不必要地将 gem 添加到您的项目中。
