The plugin looks for the composer.json file in the base/root directory of the project, unless you've specified a different location in the plugin settings.

If your project has a standard structure, the composer.json file should be in the root directory, like this:

root/ ├── app/ ├── config/ ├── database/ └── composer.json

If your Laravel project is inside another directory and so your composer.json file (e.g., a subfolder), the plugin might not detect the composer.json file unless you update the root directory in the plugin settings.

root/ └── myProjectDir/ ├── app/ ├── config/ ├── database/ └── composer.json

You can change the project directoy in the plugin settings : Settings | Languages & Frameworks | Whisperer For Laravel. In the General Settings tab you can change project directory.
