Question

当我运行lint我的打字稿代码时，它会引发解析错误：

  2:3  error  Parsing error: Only declares and type imports are allowed inside declare module

  1 | declare module "*.json" {
> 2 |   var value: any;
    |   ^
  3 |   export default value;
  4 | }

我是TypeScript的新手，真的不确定如何解决此问题吗？

我的tsconfig如下：

{
  "compilerOptions": {
    "isolatedModules": true,  // Warn you if you write certain code that can’t be correctly interpreted by a single-file transpilation process.
    "outDir": "./dist/",
    "module": "commonjs",
    "target": "ES5",
    "jsx": "react",
    "lib": ["ESNEXT", "DOM", "DOM.Iterable", "ES5"],
    "allowJs": true, // Allow JavaScript files to be imported inside your project, instead of just .ts and .tsx
    "checkJs": true,  // When checkJs is enabled then errors are reported in JavaScript files. This is the equivalent of including // @ts-check at the top of all JavaScript files which are included in your project.
    "allowSyntheticDefaultImports": true, // Allow default imports from modules with no default export
    "skipLibCheck": true,
    "types": ["node", "webpack-env", "@wdio/sync", "mocha", "expect-webdriverio"],
    "strict": false // Enables all strict type checking options (This is too restrictive for the current code base)
  },
  "include": [
    "src/**/**.ts",
    "test/**/**.ts"
  ]
}

我应该排除它吗？这是Webpack的React代码库。

error  Parsing error: Only declares and type imports are allowed inside declare module

答案就在于错误本身。

declare module是用来声明类型的，但是您在代码中所做的就是定义一个变量（值不是类型），因此这是不允许的，也没有任何意义。只需删除该行，错误就会消失。

如果您能说出您实际想要达到的目标，我们可以为您提供帮助。
