  stay   Is not listed within the file to add or modify a regular path to the include in the file indicated.

At present, the file indicating the path regularity problem is tsconfig.json, so go to the tsconfig.json file to view the include item.

tsconfig.json：

{
  "include": ["src"],
}

{
  "include": ["src/**/*.ts"],
}
