Laravel: How to fix the MySQL related "Specified key was too long error" error in Laravel

This is a common problem (especially if you use a local development environment such as XAMPP).

The error will look something like this:

[Illuminate\Database\QueryException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

 [PDOException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

Luckily the fix is simple. Add the following to the boot() method of your app/Providers/AppServiceProvider.php file:

  1. Schema::defaultStringLength(191);
