Question

Rails 5.1.5 webpacker 3.3.0

当我运行 rails 应用程序时，出现此编译错误并且无法运行。

Compilation failed:

Answer 1

我自己找到了解决方案。

已将 set 更改为 config/webpack/environment.js 的 prepend。

之前

environment.plugins.set('Provide',
  new webpack.ProvidePlugin({
    $: 'jquery',
    jQuery: 'jquery'
  })
)

之后

environment.plugins.prepend('Provide',
  new webpack.ProvidePlugin({
    $: 'jquery',
    jQuery: 'jquery'
  })
)
