“Heroku上的Node.js入门”时的工头错误

Question

我正处于“Heroku上的Node.js入门”中，我希望通过以下方式“在本地运行应用程序”： $ foreman start web （参见https://devcenter.heroku.com/articles/getting- start-with-nodejs＃run-the-app-local ）

它说：/usr/local/foreman/lib/foreman/process.rb：54： run': undefined method spawn'for Process：来自/usr/local/foreman/lib/foreman/process.rb的模块（NoMethodError） ：53： chdir' from /usr/local/foreman/lib/foreman/process.rb:53:in运行'来自/usr/local/foreman/lib/foreman/engine.rb:356:in spawn_processes' from /usr/local/foreman/lib/foreman/engine.rb:353:in来自/usr/local/foreman/lib/foreman/engine.rb:353:in spawn_processes' from /usr/local/foreman/lib/foreman/engine.rb:352:in来自/usr/local/foreman/lib/foreman/engine.rb:352:in spawn_processes' from /usr/local/foreman/lib/foreman/engine.rb:57:in开头'from /usr/local/foreman/lib/foreman/cli.rb:41:in start' from /usr/local/foreman/vendor/gems/thor-0.19.1/lib/thor/command.rb:27:in 发送 'from /usr/local/foreman/vendor/gems/thor-0.19.1/lib/thor/command.rb:27:in run' from /usr/local/foreman/vendor/gems/thor-0.19.1/lib/thor/invocation.rb:126:in invoke_command'来自/usr/local/foreman/vendor/gems/thor-0.19.1/lib/thor.rb:359 ：从/ usr / bin / foreman dispatch' from /usr/local/foreman/vendor/gems/thor-0.19.1/lib/thor/base.rb:440:in start'：15

（在Mac OS 10.7.5上运行）

任何想法可能有什么帮助？ 谢谢！

查看https://github.com/ddollar/foreman/issues/473 。 似乎与老版本的工头或红宝石有关。
