我关于 Rails 在部署后崩溃的问题。我的部署工作正常。我用rails new myapp --database=postgresql. 然后，我提交我的更改并推送到 heroku。这告诉我：

git push

所以看起来一切正常，但是当我访问我的 heroku 应用程序时，我得到一个错误页面。

运行后heroku logs，我看到以下内容：

看起来你需要添加

gem thread_safe

到您的 GemFile 并重新运行

bundle

但是，如果heroku logs --tail运行日志或heroku logs -n 500特定行数有其他错误，应该有助于获得更多详细信息

我不使用 Rails，但我在 heroku 上的节点上遇到了类似的问题——我忘记将依赖项保存到我的 package.json 文件中，而 heroku 不知道下载它。似乎您在使用主动支持 gem 时遇到了同样的问题。

仅供参考，您是否将您的 ruby​​ 版本添加到您的 Gemfile 中？
像这样的东西。。

--------- 宝石文件 ---------------------------------

source 'https://rubygems.org'
ruby "2.0.0"

gem list ....

确保你再次捆绑，希望有所帮助..
