Question

我正在制作我的第一个typescript-node-express应用程序。

首先，我创建了自己的tsconfig文件，看起来像

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs", 
    "strict": true,
    "baseUrl": "./",
    "outDir": "./build",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "importHelpers": true,
    "types": [
      "node"
    ],
    "typeRoots": [
        "node_modules/@types"
    ],
    "include": [
      "src/**/*.ts"
    ],
    "exclude": [
      "node_modues"
    ]
  }
}

在我的src / app.ts中，我正在初始化我的快递应用

import * as express from "express";

class App {

  constructor() {
    this.app = express();
  }

  //TODO: What is public app: express.Application
  public app: express.Application;

}

const app = new App().app;
const port = 4040;

app.listen(port, function() {
  console.log('Express server listening on port ' + port);
});

现在，当我执行ts-node ./src/app.ts时，出现以下错误

错误TS5023：未知的编译器选项'include'。

错误TS5023：未知的编译器选项'排除'。

有人可以帮我弄清楚为什么我会收到此错误吗？

Answer 1

根据the handbook，include和exclude应该是compilerOptions的兄弟姐妹，而不是孩子：

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs", 
    "strict": true,
    "baseUrl": "./",
    "outDir": "./build",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "importHelpers": true,
    "types": [
      "node"
    ],
    "typeRoots": [
        "node_modules/@types"
    ]
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modues"
  ]
}

Answer 2

问题是因为它们根本不属于编译器选项。

它们应与编译器选项一起存在，如下所示：

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs", 
    "strict": true,
    "baseUrl": "./",
    "outDir": "./build",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "importHelpers": true,
    "types": [
      "node"
    ],
    "typeRoots": [
        "node_modules/@types"
    ]
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modues"
  ]
}

Answer 3

如果您在 100% 验证您的 exclude 或 include 选项不在 compilerOptions 范围内后仍然收到此错误，您可能忘记检查两者tsconfig.json 和 tsconfig.app.json 继承自前者。

值得花一些时间查看 official docs。
