运行rails应用程序时出现webpacker错误。 'TypeError：environment.plugins.set不是函数'

Question

Rails 5.1.5 webpacker 3.3.0

当我运行rails应用程序时，我收到此编译错误，但它无法正常工作。

Compilation failed:
remote:        /tmp/build_074ca0ee678491d6f72035c60cc5f616/config/webpack/environment.js:5
remote:        environment.plugins.set('Provide',
remote:        ^
remote:        TypeError: environment.plugins.set is not a function
remote:        at Object.<anonymous> (/tmp/build_074ca0ee678491d6f72035c60cc5f616/config/webpack/environment.js:5:21)
remote:        at Module._compile (module.js:643:30)

Answer 1

我自己找到了解决方案。

将set改为prepend的config/webpack/environment.js。

之前

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

后

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