我制作了一个新的 Rails 4 beta 应用程序并将其部署到 Heroku(使用 Ruby 2.0.0,并通过 Procfile 使用 Unicorn)。
它在本地运行良好foreman start
,但是当我访问已部署应用程序的主页时,我只收到标准 Heroku 500 错误:
We're sorry, but something went wrong.
If you are the application owner check the logs for more information.
但是,在日志中,没有错误。我不知道是什么导致了 500。
这是我上次的输出git push heroku master

之后,我尝试在浏览器中加载主页,这些是日志中出现的仅有的两行:

有谁知道问题可能是什么?
其他可能相关的事情:
- 我已经禁用了标准的 Heroku Postgres 插件,而改用 ClearDB MySQL 插件。
- 我尝试手动将
DATABASE_URL
环境变量从以前的值(即使我删除了 postgres 插件后仍然是 postgres URL)更改为与CLEARDB_DATABASE_URL
var(mysql 的值)相同的值。这似乎没有任何区别。 - 我已添加
ruby '2.0.0'
到我的 Gemfile 中,并添加了mysql2
和unicorn
gems。我已经使用了https://devcenter.heroku.com/articles/rails-unicornconfig/unicorn.rb
上的建议 - 我的 Procfile 仅包含:
web: bundle exec unicorn -p $PORT -E $RACK_ENV
- 它在本地与
foreman start
. - 除了上述修改之外,它基本上是一个使用
rails new
.
