我想在 Amazon Elestic Beanstalk 上托管我的 rails 网站。我遵循了本指南：http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/create_deploy_Ruby_rails.html。

现在，我遇到了这个错误：无法启动 Ruby (Rack) 应用程序

【解决方案1】：

我正在经历这种情况，并发现这与 rake 本身无关。发生这种情况可能是因为您的其中一个 gem 没有安装。在我的例子中，它是 pg 没有被安装，因为它需要 pg_config 可执行文件。

所以，就我而言，为了解决这个问题，我将以下部分添加到 .ebextensions/default.config：

packages:
  yum:
    git: []
    postgresql-devel: []

# Run rake tasks before an application deployment
container_commands:
  01bundler-pg:
    command: bundle config build.pg --with-pg-config=/usr/bin/pg_config

即使您不使用 pg，请检查您的任何 gem 是否需要安装开发头文件或可执行文件。
