Question

我正在努力将现有应用程序升级到最新版本，并在下面的以下错误上粘贴。我在这里找到了一些示例 1 | 2 | 3 ----不幸的是，这些示例没有工作为我。

*当前错误：

Sprockets::Rails::Helper::AssetNotPrecompiled - chartkick.js:
  app/views/layouts/application.html.haml:5:in '_app_views_layouts_application_html_haml__3032669070778132401_2208319440'

有关如何解决ChartKick.js的任何建议？
