How can i ignore the warning when i deleted a piece manually from my apostrophe-project?

Question

I have deleted a piece from my apostrophe project manually. now when i run the project it is shows as a warning that: It looks like you may have made a mistake in your code:

The module banners does not extend anything and does not have a beforeConstruct, construct or afterConstruct function. This usually means that you:

1. Forgot to extend another module

The module banners does not extend anything and does not have a beforeConstruct, construct or afterConstruct function. This usually means that you:

1. Forgot to extend another module
2. Configured a module that comes from npm without npm installing it
3. Simply haven't written your index.js yet

If you really want a module with no code, set the ignoreNoCodeWarning option to true for this module.

What should i do to ignore this warning?
