【中文标题】带有nestjs的Angular-universal:错误:找不到模块\'./drivers/node-mongodb-native/connection\'【英文标题】:Angular-universal with nestjs: Error: Cannot find module './drivers/node-mongodb-native/connection'带有nestjs的Angular-universal:错误:找不到模块'./drivers/node-mongodb-native/connection' 【发布时间】:2020-04-08 08:58:57 【问题描述】:我将 Angular-universal 与 Nest-js 一起使用,它在本地运行良好,但是当我将它部署到 Heroku 上时,我收到了这个错误:
Error: Cannot find module './drivers/node-mongodb-native/connection'.
我不知道是什么原因造成的。 这是我的 package.json:

【问题讨论】:
【参考方案1】:我临时固定添加,在路径\node_modules@nestjs\ng-universal\dist\webpack-config.factory.js,mongoose|mongodb到
whitelist: /^(?!(@nestjs\/(common|core|microservices)|livereload|concurrently)).*/
这样
whitelist: /^(?!(@nestjs\/(common|core|microservices)|livereload|concurrently|mongoose|mongodb)).*/
或者用这种方式更新webpack.config.js
const webpack = require('webpack');
const WebpackConfigFactory = require('@nestjs/ng-universal')
.WebpackConfigFactory;
const nodeExternals = require('webpack-node-externals');
const webpackOptions = WebpackConfigFactory.create(webpack,
server: './server/main.ts',
prerender: './prerender.ts',
);
const whitelistedPackages = /^(?!(@nestjs\/(common|core|microservices)|livereload|concurrently|mongoose|mongodb)).*/;
webpackOptions.externals[1] = nodeExternals(
whitelist: whitelistedPackages,
);
webpackOptions.plugins.push(
new webpack.IgnorePlugin(
checkResource(resource)
const lazyImports = [
'@nestjs/microservices',
'cache-manager',
'class-validator',
'class-transformer',
];
if (!lazyImports.includes(resource))
return false;
try
require.resolve(resource);
catch (err)
return true;
return false;
,
),
);
module.exports = webpackOptions;
