ruby-on-rails - 在 Heroku 上获取 "/usr/bin/env: ruby.exe: No such file or directory"

Question

刚刚部署了一个应用程序，但我得到的在线消息是:

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details."

这是日志中的示例，但我无法找出问题所在。

在尝试了到目前为止我得到的所有建议并相应地完成了所有更改之后，这就是我在 heroku 日志中得到的:

Answer 1

您需要在应用程序的第一行更改 3 个文件:
箱/捆
箱子/rails
仓/rake


改变

#!/usr/bin/env ruby.exe

到

#!/usr/bin/env ruby

那是错误!

你通常可以做的:

heroku run rake db:migrate
