json - Angular 8和导入Json

Question

我已经阅读了几篇文章，指出自2.9版脚本以来，您现在可以直接导入json。
因此，我对 tsconfig.json 文件进行了如下修改:

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  },
  "paths": {
    "@data/*": ["src/core/data/*"],
    "@models/*": ["src/core/models/*"],
    "@services/*": ["src/core/*"],
    "@environments/*": ["src/environments/*"]
  },
  "resolveJsonModule": true,
  "esModuleInterop": true,
  "allowSyntheticDefaultImports": true
}

然后将json导入到我的组件中，如下所示:

import particlesJson from '../../assets/particles.json';

它运行正常，但在控制台中出现错误:

ERROR in src/app/profile/login.component.ts(3,27): error TS2732: Cannot find module '../../assets/particles.json'. Consider using '--resolveJsonModule' to import module with '.json' extension

如何阻止该错误出现？

Answer 1

"resolveJsonModule": true,
"esModuleInterop": true,

根据文档，应将其放在 compilerOptions中的 tsconfig.json下。
参见示例 here。
