我的webpack.config.js
是:
const path = require('path');
module.exports = {
entry: './app.ts',
target: 'node',
node: {
__dirname: true
},
module: {
rules: [
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/,
},
],
},
resolve: {
extensions: [ '.tsx', '.ts', '.js' ],
},
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
};
构建项目并运行它时,出现以下错误:
(node:51071) UnhandledPromiseRejectionWarning: Error: Cannot find module '../gather/gatherers/css-usage'
at webpackEmptyContext (webpack:///./node_modules/lighthouse/lighthouse-core/config_sync?:2:10)
at Function.requireGathererFr
此错误是由于我正在使用的第三方库-lighthouse
引起的。
如何解决此错误?

对于作为目标的节点,可能必须使用此软件包webpack-node-externals
才能忽略node_module
文件夹中的所有模块。然后声明为externals
:
const nodeExternals = require('webpack-node-externals');
module.exports = {
externals: [nodeExternals()],
// ...
};
