我有一个 Sinatra 应用程序。添加后gem 'kaminari'，我开始收到错误

        from /usr/local/bin/rackup:23:in `<main>'

当我尝试通过 ' 启动应用程序rackup'时 以前它运作良好。

我该如何摆脱它？

它应该在 sinatra/padrino 支持gem 'kaminari', :require => 'kaminari/sinatra'的 kaminari README 部分中解释

实际上在内部需要的/lib/kaminari/helpers/sinatra_helpers.rb 文件第 128-129 行是：

$stderr.puts "[!]You should install `padrino-helpers' gem if you want to use kaminari's pagination helpers with Sinatra."
$stderr.puts "[!]Kaminari::Helpers::SinatraHelper does nothing now..."

所以我认为你应该安装 padrino-helpers。
