error TS5023: Unknown compiler option 'enableIvy'.

任何人都可以解决这个问题。

Answer 1

尝试在下面包含enableIvy选项angularCompilerOptions

"angularCompilerOptions": {
   "enableIvy": true
}

Answer 2

compilerOptions和angularCompilerOptions是在两个单独的性质tsconfig.json。您需要添加"enableIvy": true，angularCompilerOptions而不是compilerOptions：

tsconfig.json：

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