Postgresql 如何将pg promise包含在Ionic 3中？运行时错误："；无法读取属性'；拆分'；“未定义”的定义；

我正试图用pg promise将我的postgresql数据库连接到爱奥尼亚

我按照TypeScript使用说明将pg promise与TypeScript集成

当我在带有“ionic serve”的服务器上运行此操作时，控制台中出现以下错误：

Uncaught TypeError: Cannot read property 'split' of undefined  index.js:4 
at Object.<anonymous> (index.js:4)
at Object.<anonymous> (index.js:15)
at __webpack_require__ (bootstrap 25deb0d8315dc2a84252:54)

at __webpack_require__ (bootstrap 25deb0d8315dc2a84252:54)
at Object.317 (main.js:675)

这是我的配置（tsconfig.json）：

以下是我的系统信息：

最后，如果我尝试在Android上运行，我会出现以下错误：

您是否正在尝试在客户端运行pg promise？这并不是为了这个，因为pg promise严格来说是一个服务器端包。
