Question

我正在运行OS X，10.11.2（15C50），rvm 1.26.11，ruby 2.3.0p0和gem 2.5.1。如果我尝试运行rails g controller welcome或任何其他生成命令，我会收到以下错误。

我已经完成了rvm内爆，从头开始安装ruby，rails，bundler。创建了一个新的应用程序，问题仍然存在。

% rails g controller welcome

Answer 1

我遇到了同样的问题，我做了以下事情来解决问题：

bundle install --binstubs

首先尝试，然后尝试运行：

bundle exec rails g controller welcome

希望它有所帮助。

Answer 2

所以bundle exec rails s似乎是修复。我想我需要理解为什么我需要使用bundle exec而不仅仅是rails s。是时候阅读手册了:)）

谢谢大家

无法运行生成bundler / setup（LoadError）
