tsconfig.json 与 node.js 模块一起使用的最佳设置是什么？

Question

到目前为止，我在“./src”中有 2 个文件： index.ts和setConfig.ts 。 像这样导入'fs'和'path'：

const fs = require('fs');
const path = require('path');

...这就是 Typescript 显然不喜欢的； 编译时说：

src/index.ts:1:7 - error TS2451: Cannot redeclare block-scoped variable 'fs'.

1 const fs = require('fs');
        ~~

  src/setConfig.ts:1:7
    1 const fs = require('fs');
            ~~
    'fs' was also declared here.

src/index.ts:2:7 - error TS2451: Cannot redeclare block-scoped variable 'path'.

2 const path = require('path');
        ~~~~

  src/setConfig.ts:2:7
    2 const path = require('path');
            ~~~~
    'path' was also declared here.

src/setConfig.ts:1:7 - error TS2451: Cannot redeclare block-scoped variable 'fs'.

1 const fs = require('fs');
        ~~

  src/index.ts:1:7
    1 const fs = require('fs');
            ~~
    'fs' was also declared here.

src/setConfig.ts:2:7 - error TS2451: Cannot redeclare block-scoped variable 'path'.

2 const path = require('path');
        ~~~~

  src/index.ts:2:7
    2 const path = require('path');
            ~~~~
    'path' was also declared here.


Found 4 errors.

但是当我在setConfig.ts中忽略它时，节点抱怨它不知道'fs'......

我的tsconfig.json看起来像这样：

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "outDir": "./dist/",
    "rootDir": "./src/", 
    "strict": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true
  }
}

那么，我还需要添加什么或做什么才能使我编译的 JavaScript 正常工作？

在setConfig.ts模块中添加导出应该可以解决问题。

// setConfig.ts
export default {
  // your exports
};
// Or
export function foo() {}
