每当我使用 rails new project_name 在 rails 中创建新项目，然后在 localhost:3000 启动我的服务器时，我总是收到以下错误:

所有现有项目都可以正常启动。只影响新的。在此错误之前，我没有安装任何 gem 或任何应用程序。只是突然发生了。如果有人可以提供帮助，将不胜感激，谢谢!

最佳答案

试试这个，看看它是否有效。转到您的 Gemfile.lock 并找到 rack (1.6.3) 将其更改回 rack (1.6.2)。 Bundler 对此进行了更新。然后重试。

关于ruby-on-rails - Rails - 每次我创建一个新项目时，我都会得到 : Error during failsafe response: wrong number of arguments (2 for 1)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30925895/
