Setting the "config.fxp-asset.installer-paths" option in the composer

Question

When I run composer update, I get the following warning before it continues with the update.

The "extra.asset-installer-paths" option is deprecated, use the "config.fxp-asset.installer-paths" option

Where / how can I change these settings?

Answer 1

Replace the section extra.asset-installer-pathswith:

    "config": {
        "fxp-asset": {
            "installer-paths": {
                "npm-asset-library": "vendor/npm",
                "bower-asset-library": "vendor/bower"
            }
        },
    }
