错误 TS5023：未知的编译器选项“enableIvy”

Question

我正在尝试将 IVY 添加到我的 Angular 7 beta 项目中。所以，我在compilerOptions 部分中将enableIvy: true 添加到src/tsconfig.app.json

但是当我运行 ng build --prod --aot --output-hashing none 时，我得到以下错误。

error TS5023: Unknown compiler option 'enableIvy'.

Error: error TS5023: Unknown compiler option 'enableIvy'.

任何人都解决了这个问题。

Answer 1

尝试在angularCompilerOptions下包含enableIvy选项

"angularCompilerOptions": {
   "enableIvy": true
}

Answer 2

现在设置正确的方式

"angularCompilerOptions": {
   "enableIvy": "ngtsc"
}

这与问题#23455有关

此提交添加了一个不依赖于全局的新编译器管道 分析，称为“ngtsc”。这个新的编译器由 运行 ngc 并将“enableIvy”设置为“ngtsc”。它重用相同的初始化 逻辑，但创建一个新的 Program 实现，它不执行 AngularCompilerProgram 所做的全局级分析。这将是 生产常春藤编译器的基础。

Answer 3

compilerOptions 和 angularCompilerOptions 是 tsconfig.json 中的两个独立属性。您需要将"enableIvy": true 添加到angularCompilerOptions 而不是compilerOptions：

tsconfig.json：

{
  "compilerOptions": {
  ....
  },
  "angularCompilerOptions": {
    "enableIvy": true
  }
}
