基于jhipster的nhipster服务器启动错误

Question

我正在尝试使用 Jhipster（即 nhipster）生成基于 Angular NestJS 的应用程序。 以下是我的 jhipster 和 nodejs 版本号：

Jhipster : 7.7.0 NodeJS: 16.14.0 LTS

但是当我尝试启动服务器时出现以下错误：

错误：

Answer 1

“56”行的“URL”函数未正确导入到打字稿模块中。它是来自 typescript 编译器内部 dom 定义的函数。您可以找到一种方法将其导入 header-util 类。另一种方法，我要做的就是在服务器 ts-config 文件的编译器选项中启用“dom”，通过将“dom”添加到 lib 数组中，如下所示：

{
  "compilerOptions": {
   /* Basic Options */
     "typeRoots": ["node_modules/@types"],
     "target": "ES2017" /* Specify ECMAScript target version: 'ES3' (default), 
     'ES5', 'ES2015', 'ES2016', 'ES2017','ES2018' or 'ESNEXT'. */,
     "module": "commonjs" /* Specify module code generation: 'none', 'commonjs', 
     'amd', 'system', 'umd', 'es2015', or 'ESNext'. */,
     "lib": [
          "es6",
          "dom"    /* <--- here you are */
     ]
     ...
     }
