angular universal connected postgresql问题

Question

I npm在angular universal上安装pg，修改Server.ts导入pg以连接postgresql，npm运行dev:ssr，错误显示如下。找不到模块:错误:无法在'D:\gitapp\ngex\node_modules\pg\lib\native‘中解析' pg-native’在'D:\gitapp\ngex\node_modules\pg\lib\native‘中解析'pg-native’，我尝试npm安装pg-native，但未能成功。但如果在一个纯打字快捷键上连接pg，就没有错误了。

 import * as pg from 'pg';
const config = { 
    host: '192.168.0.1', 
    user:"postgres",
    database:"pgdata",
    password:"pg123456",
    port:5432,
     max:20,
    idleTimeoutMillis:3000,
   };
   const pool = new pg.Pool(config);

已经解决了，我只是在github上检查了angular universal，有人也有这个问题，为了解决这个问题，你可以使用externalDependencies选项。它可以在angular.json中配置。"server": { "builder": "@angular-devkit/build-angular:server", "options": { "outputPath": "dist/server", "main": "server.ts", "tsConfig": "tsconfig.server.json", "externalDependencies": [ "pg" ] }, ... }
