Foreman gem的rackup文件无效

Question

尝试在流浪汉上运行工头启动(Ubuntu)。

Procfile

web:            bundle exec thin start --port 3000
private_pub:    bundle exec thin start --port 9292 --rackup private_pub.ru

private_pub.ru在我的根目录下，Procfile也在根目录下。

如果我这样做(它起作用了)：

rackup private_pub.ru -s thin -E production

在rails服务器之后...

但是当我这样做的时候：

foreman start

20:43:18 private_pub.1  | started with pid 3450

问题出在Vagrant身上。您的Procfile (在Windows下克隆)具有Windows行结尾(\r\n)。这使得thin看到'private_pub.ru\r‘作为它的rackup文件，这是由于文件末尾的换行符，所以这里的测试：https://github.com/macournoyer/thin/blob/master/lib/thin/controllers/controller.rb#L176失败。

删除换行符以解决问题。
