Laravel, composer install causes an error in PackageManifest, so resolve it

I'm using a slightly older version of Laravel and when I do composer install, I get an error with php artisan package: discover. Upon examination, I found that composer had changed the format of vendor / composer / installed.json in version 2.0 and later, causing an error. I'll leave it as a memo because many people are likely to stumble.

Error and stack trace

php artisan package:discover
