ruby-on-rails - Rails 错误:未初始化常量 Sass::Plugin (NameError)

Question

在使用脚手架创建一些代码后，我遇到了一个奇怪的错误。以下错误现在出现在任何新的生成或销毁命令上。

$ rails destroy 脚手架插件

Answer 1

根据错误日志，您可以尝试两种选择:

1) Comment one line something like gem 'sass' in Gemfile due to name conflict of Plugin 
2) Configure Sass gem properly

那么您很可能能够正确运行新的生成和销毁命令。
