webpack-dev-server - 无效的配置对象 : webpack. server.js

Question

我在使用这个 webpack 文件时遇到错误。

这是 webpack 文件:

const path = require('path');
module.exports = {
target: 'node',
entry: './src/index.js',
output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'build')
},
module: {
    rules: [
        {
            test: /\.js?$/,
            loader: 'babel-loader',
            exclude: /node_modules/,
            options: {
                presets: [
                    'react',
                    'stage-0',
                    ['env', { targets: { browsers: ['last 2 versions']}}]
                ]
            }
        }
    ]
  }
}

这是错误信息:

Invalid configuration object. Webpack has been initialised using a 
    configuration object that does not match the API schema.
    - configuration.context: The provided value 
    "C:\\Users\\}\\Desktop\\Node\\HelloWorld!\\new" contains exclamation mark 
    (!) which is not allowed because it's reserved for loader syntax.
    -> The base directory (absolute path!) for resolving the `entry` option. If 
    `output.pathinfo` is set, the included pathinfo is shortened to this 
    directory.
    - configuration.output.path: The provided value 
    "C:\\Users\\}\\Desktop\\Node\\HelloWorld!\\new\\build" contains
    exclamation mark (!) which is not allowed because it's reserved for loader 
     syntax.
    -> The output directory as **absolute path** (required).

同样的错误。问题似乎出在您的文件夹路径中。它不得包含感叹号 (!)。更改文件夹“HelloWorld!”只是没有感叹号的“HelloWorld”。

希望这能解决问题。
