ruby-on-rails – 工头启动错误(server.rb：33,缺少参数……)

在尝试启动工头后,我得到了这个错误(请注意,它似乎确实在heroku上工作,所以我猜这是一个严格的本地问题)：

Procfile只有一行为specified by heroku

web: bundle exec rails server thin -p $PORT -e $RACK_ENV

我的gemfile有

gem 'thin'

Google对此错误的帮助不大.

谢谢！

解决方法

这不是关于在Heroku上执行 – 看到关于执行Foreman的原始问题 – 这是本地执行.

您可以通过执行以下操作来复制错误：

rails server thin -e

鉴于您的Procfile,这实际上是Foreman正在运行的：

web: bundle exec rails server thin -p $PORT -e $RACK_ENV

所以我猜你没有把参数传给-e.即.你还没有在本地定义RACK_ENV.

你可以做的是在你的本地目录中创建一个.env文件,例如

RACK_ENV=development

PORT=3000

在根据您的流程类型声明创建流程之前,Foreman将自动获取本地.env文件并适当地设置环境.
