npx webpack 报错我实在找不出原因

const path = require('path')
const nodeExternals = require('webpack-node-externals')
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
debugger
const webpackconfig = {
    target: 'node',
    mode: 'development',
    entry: {
        server: path.join(__dirname, 'src/index.js')
    },
    output: {

我跟你一样的配置，没有打包出现错误：

package.json

{
"name": "webpack-demo",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"@babel/core": "^7.7.7",
"babel-loader": "^8.0.6",
"clean-webpack-plugin": "^3.0.0",
"webpack": "^4.41.5",
"webpack-cli": "^3.3.10",
"webpack-node-externals": "^1.7.2"
}
}

webpack.config.js

const path = require('path')
const nodeExternals = require('webpack-node-externals')
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
const webpackconfig = {
target: 'node',
mode: 'development',
entry: {
server: path.join(__dirname, 'src/index.js')
},
output: {
filename: '[name].bundle.js',
path: path.join(__dirname, './dist')
},
devtool: 'eval-source-map',
module: {
rules: [
{
test: /\.(js|jsx)$/,
use: {
loader: 'babel-loader'
},
exclude: [path.join(__dirname, '/node_modules')]
}
]
},
externals: [nodeExternals()],
plugins: [
new CleanWebpackPlugin()
],
node: {
console: true,
global: true,
process: true,
Buffer: true,
__filename: true,
__dirname: true,
setImmediate: true,
path: true
}
}
 
module.exports = webpackconfig

node, nvm版本：

➜ node -v

v12.13.1

➜ nvm --version

0.35.1
