`parse_rackup_file’:rackup文件(config.ru)不可读(ArgumentError)

我的proc文件中有这个“web:bundle exec unicorn -p $ PORT -c ./config/unicorn.rb”。

启动服务器后,我收到以下错误消息。

foreman start 12:29:20 web.1 | started with pid 4876 12:29:20 web.1 | exited with code 1 12:29:20 system | sending SIGTERM to all processes 12:29:20 | /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/lib/unicorn/configurator.rb:659:in `parse_rackup_file': rackup file (config.ru) not readable (ArgumentError) 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/lib/unicorn/configurator.rb:77:in `reload' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/lib/unicorn/configurator.rb:68:in `initialize' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/lib/unicorn/http_server.rb:108:in `new' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/lib/unicorn/http_server.rb:108:in `initialize' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/bin/unicorn:126:in `new' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/gems/unicorn-4.7.0/bin/unicorn:126:in `' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/bin/unicorn:19:in `load' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/bin/unicorn:19:in `' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3- p448@cpi2/bin/ruby_executable_hooks:15:in `eval' 12:29:20 | from /home/stcadmin/.rvm/gems/ruby-1.9.3-p448@cpi2/bin/ruby_executable_hooks:15:in `' 12:29:20 | master failed to start, check stderr log for details 

我目前的应用程序是在Rails 2.3.18中。

最后添加“-E development -D”之类的东西。
