ruby-on-rails - Elastic Beanstalk Ruby/Rails 需要安装 git 所以 bundle install 可以工作..但不是

Question

我在部署我们的 Rails 应用程序时遇到问题。我创建了一个类似于 AWS 博客 howto 上示例的 Hook http://ruby.awsblog.com/post/Tx2AK2MFX0QHRIO/Deploying-Ruby-Applications-to-AWS-Elastic-Beanstalk-with-Git喜欢:

packages:
  yum:
    git: []

甚至我运行一个 bundle 来创建 vendor/cache 以将所有 gems 都放在那里......并且仍然得到:git://github.com/refinery/refinerycms-search.git(在 2-0-stable)未 checkout 。请运行 bundle install (Bundler::GitError)

任何帮助都会很好，我们正在努力将我们所有的应用程序转移到 EB。但看到 git 没有安装或正在发生某些事情。我需要在它创建的 EB ec2 实例上使用 git。

堆栈跟踪:

更新更多信息:我决定使用 ec2-user 登录实例并注意到git 已安装到目前为止，我所看到的我需要的 gem 已经安装好了。当我执行捆绑列表时，它们甚至都显示了错误所提示的那个。我确实注意到，当我执行一般 gem 列表时然后它不会出现...但它应该使用 bundle 。

(请注意，仅当您必须使用 Git 源作为依赖项时，才应使用以下解决方法。如果可以避免，建议不要从外部 Git 存储库安装依赖项。请参阅下面详细介绍了为什么会这样。)

在带有 Passenger 的 Gemfile 中使用 Git 支持的库时，您必须在安装中禁用共享 gem(除了在上面列出的 Hook 中安装 Git 之外)。您可以通过在现有 .ebextensions/ruby.config 文件中设置 BUNDLE_DISABLE_SHARED_GEMS Bundler 环境变量来执行此操作，如下所示:

option_settings:
  - option_name: BUNDLE_DISABLE_SHARED_GEMS
    value: "1"
  - option_name: BUNDLE_PATH
    value: "vendor/bundle"

packages:
  yum:
    git: []

禁用共享 gem 将强制所有依赖项按照 BUNDLE_PATH 变量的指定在 vendor/bundle 中供应到您的应用程序中。

请注意，只要有可能，您应该避免在您的应用程序中安装来自 Git 源的公共(public)库。将 Git 用于库位置会为部署安装引入另一个故障点，因为 Git 存储库可能暂时不可用甚至永久移动。另请记住，在部署中强制安装供应商将导致您的 Elastic Beanstalk 部署在后续部署具有相同依赖项的应用程序时速度要慢得多。这是因为库将在每次部署时重新安装，而不是利用 Elastic Beanstalk 让 Bundler 默认执行的系统范围安装。

简而言之，如果有问题库的官方 RubyGem 版本，您应该改用那个版本；如果没有，您应该向库作者建议提供官方 RubyGem 版本。

仅供引用，之前有人问过一个关于常规 Passenger/Rails 部署的 Git 问题的类似问题:Rails 3: Passenger can't find git gems installed by bundler
