Question

为什么偷看宝石显示uninitialized constant Peek::Views::Mysql2 (NameError)。按照文档https://github.com/peek/peek中的步骤操作。 Addedmount Peek :: Railtie =＆gt; ＆＃39; / PEEK＆＃39;

  root :to => 'home#show'

Gem也存在于本地gemset中

config/initializers/peek.rb:1:in `<top (required)>': uninitialized constant Peek::Views::Mysql2 (NameError)

Answer 1

在Gemfile中添加peek-mysql2 gem。

对于Peek.into ...文件中的每个config/initializers/peek.rb语句，都应包含corresponding gem containing the view files。

Peek因未初始化的常量错误而失败
