启动 Angular 11 项目时出现 tsconfig 错误

Question

I just create a project didn't do any changes. It shows error in tsconfig.json file. I tried to fix this by changing the es2020 into es2015 but it did not fix the error

TS6046: Argument for '--module' option must be: 'none', 'commonjs', 'amd', 'system', 'umd', 'es6', 'es2015', 'esnext'.

Here is my tsconfig.json

 {
  "compileOnSave": false,
  "compilerOptions": {
  "baseUrl": "./",
  "outDir": "./dist/out-tsc",
  "forceConsistentCasingInFileNames": true,
  "strict": true,
  "strictPropertyInitialization": false,
  "noImplicitReturns": true,
  "noFallthroughCasesInSwitch": true,
  "sourceMap": true,
  "declaration": false,
  "downlevelIteration": true,
  "experimentalDecorators": true,
  "moduleResolution": "node",
  "importHelpers": true,
  "target": "es2015",
  "module": "es2020",
  "lib": [
    "es2018",
    "dom"
  ]
},
 "angularCompilerOptions": {
   "enableI18nLegacyMessageIdFormat": false,
   "strictInjectionParameters": true,
   "strictInputAccessModifiers": true,
   "strictTemplates": true
}
}

How can I solve this.

Answer 1

update your tsconfig.app.json file as well with "module": "es2015"

Answer 2

I think the problem is that Angular needs :

"module": "amd",

While Lit needs one of the ES module variants.
