我正在尝试运行我自己的 webpack-4 + vue 应用程序。有了这个package.json。我希望如果我实现了这一目标,我可以将其与现有的 ASP.Net-Core 应用程序集成

webpack.config.js

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const bundleOutputDir = 'dist';
const { VueLoaderPlugin } = require('vue-loader')

module.exports = (env) => {
const isDevBuild = !(env && env.prod);

return [{
stats: { modules: false },
context: __dirname,
resolve: { extensions: ['.js'] },
entry: { 'main': './src/index.js' },
module: {
rules: [
{ test: /\.vue\.html$/, include: /ClientApp/, loader: 'vue-loader', options: { loaders: { js: 'awesome-typescript-loader?silent=true', loader: "unicode-loader" } } },
// { test: /\.ts$/, include: /ClientApp/, use: 'awesome-typescript-loader?silent=true' },
{ test: /\.css$/, use: isDevBuild ? ['style-loader', 'css-loader'] : ExtractTextPlugin.extract({ use: 'css-loader?minimize' }) },

},
output: {

},
plugins: [
new VueLoaderPlugin(),
// new CheckerPlugin(),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: (isDevBuild ? 'development' : 'production')
}
})/* ,
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./dist/vendor-manifest.json')
}) */
].concat(isDevBuild ? [
// Plugins that apply in development builds only
new webpack.SourceMapDevToolPlugin({
filename: '[file].map', // Remove this line if you prefer inline source maps
moduleFilenameTemplate: path.relative(bundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk
})
] : [
// Plugins that apply in production builds only
new webpack.optimize.UglifyJsPlugin(),
new ExtractTextPlugin('site.css')
])
}];
};

App.vue

<template>
<div class="example">{{ msg }}</div>
</template>

<script>
export default {
data () {
return {
msg: 'Hello world!'
}
}
}
</script>

<style>
.example {
color: red;
}
</style>

我收到以下错误:

ERROR in ./src/components/App.vue 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
> <template>
| <div class="example">{{ msg }}</div>
| </template>
@ ./src/index.js 2:0-47 11:18-30

运行此命令node_modules\.bin\webpack --config webpack.config.js --modedevelopment它应该能够工作,但事实并非如此。

这些是规范:

  1. Node :v8.11.2
  2. webpack 4.17.2
  3. vuejs 2.5.17

还有什么想知道的,请告诉我。

最佳答案

对于遇到此问题的其他人,需要在 webpack 插件部分加载较新版本的 vue-loader:

// Required for vue-loader v15
const VueLoaderPlugin = require('vue-loader/lib/plugin')
environment.plugins.append(
'VueLoaderPlugin',
new VueLoaderPlugin()
)
