执行自定义Schematics 'my-comp'时无法解析工厂问题求助

I ran into this exact issue when building custom schematics before, and looking at your code and configuration, the problem comes down to a mismatch between your function export style and the factory path in collection.json.

Here are two straightforward fixes: #

Option 1: Update your collection.json to match the default export

Since you're using export default for your schematic function, the factory reference should point to #default instead of #myComp:

{
  "$schema": "../node_modules/@angular-devkit/schematics/collection-schema.json",
  "schematics": {
    "my-comp": {
      "description": "This schematics generate an Angular Component on the current module or in an specified one",
      "factory": "./my-comp/index#default"
    }
  }
}

Option 2: Switch to a named export in your factory code

If you prefer to keep the #myComp reference in your config, change your default export to a named export:

export function myComp(options: IFlexComponentOptions): Rule {
  return (host: Tree, context: SchematicContext) => {
    console.log("options before sanatize", options);
    // ... your existing logic
    return rule(host, context);
  };
}

Why this happens #

The Angular DevKit schematics engine looks for the exact export name you specify in collection.json. When you use export default, the internal identifier for that function is default — not the name you gave the function. Your config was trying to find a named export called myComp, which didn't exist, hence the resolution error.

Quick validation steps after fixing #

• If you're using TypeScript, make sure you've compiled your code with tsc (schematics runs against the compiled JavaScript files)
• Re-run the command: schematics .:my-comp
