typescript - 无法使用选项 'noEmit' 指定选项 'incremental'

Question

我正在开发一个 next.js 应用程序。它有以下 tsconfig.js

{
  "compilerOptions": {
    "target": "ES2018",
    "module": "esnext",
    "lib": [
      "dom",
      "es2018",
      "es2019.array"
    ],
    "jsx": "preserve",
    "sourceMap": true,
    "skipLibCheck": true,
    "strict": true,
    "esModuleInterop": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "allowJs": true,
    "forceConsistentCasingInFileNames": true,
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "incremental": true
  },
  "exclude": [
    "server",
    "next.config.js"
  ],
  "include": [
    "lib/global.d.ts",
    "next-env.d.ts",
    "**/*.ts",
    "**/*.tsx",
    "**/*.js"
  ]
}

它在开发模式下运行良好，但在创建构建时显示以下错误:

ERROR in tsconfig.json
22:5 Option 'noEmit' cannot be specified with option 'incremental'.
    20 |     "resolveJsonModule": true,
    21 |     "isolatedModules": true,
  > 22 |     "noEmit": true,
       |     ^
    23 |     "incremental": true
    24 |   },
    25 |   "exclude": [

Next.js 自动在 tsconfig.json 中注入(inject) 'noEmit: true'文件。虽然我真的需要增量模式来加快构建速度。有什么办法可以解决这个问题？

TS 4.0+--incremental与 --noEmit is possible现在:

"compilerOptions": {
  "noEmit": true,
  "incremental": true,
  // "tsBuildInfoFile": "/tmp/my-proj/tsbuildinfo" // custom build info file path
  // ...
}

构建信息文件 is emitted即使是 noEmit .您可以通过 --tsBuildInfoFile 设置其显式位置.否则 outDir - 如果仍然设置 - 或 tsconfig.json项目根被视为发射目录。
旧版本(解决方法)

  "compilerOptions": {
    "incremental": true,
    "declaration": true,
    "emitDeclarationOnly": true, // to emit at least something
    // "noEmit": true,
    // ...
    
    // Either set overall output directory
    "outDir": "dist",
    //  or separate locations for build file and declarations 
    // "declarationDir": "dist"
    // "tsBuildInfoFile": "/tmp/my-proj/tsbuildinfo"
  }

Allow noEmit and composite together in 3.7 #33809

.tsbuildinfo file should be created when the noEmit flag is enabled #30661
