工头无法启动

Question

有人看过吗？突然间我无法启动工头并收到此错误。

20:58:18 web.1 | started with pid 23100
20:58:19 web.1 | /Users/me/.rvm/gems/ruby-2.1.1/gems/railties-3.2.11/lib/rails/commands/server.rb:33:in parse!': missing argument: -e (OptionParser::MissingArgument)

顺便说一句，手动启动工作正常。这是我正在运行的：

Rails 3.2.11
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin12.0]
foreman (0.76.0)
thor (0.19.1)
dotenv (1.0.2) 

Answer 1

不知何故，包含所有环境设置的 .env 文件都被删除了。重新创建文件后，一切正常。
