webpack.config.js
是:
const path = require('path');
module.exports = {
entry: './app.ts',
target: 'node',
node: {
__dirname: true
},
module: {
rules: [

此错误来自我正在使用的第三方库-lighthouse
如何修复此错误?对于目标as节点,您可能必须使用此软件包
网页包节点外部
,以便忽略节点\模块
文件夹中的所有模块。然后声明为externals
:
const nodeExternals=require('webpack-node-externals');
module.exports={
外部:[nodeExternals()],
// ...
};
