Github “fatal: remote origin already exists”

As the error message indicates, there is already a remote configured with the same name. So you can either add the new remote with a different name or update the existing one if you don’t need it:

To add a new remote, called for example github instead of origin (which obviously already exists in your system), do the following:

$ git remote add github git@github.com:ppreyer/first_app.git

Remember though, everywhere in the tutorial you see “origin” you should replace it with “github”. For example $ git push origin master should now be $ git push github master.

However, if you want to see what that origin which already exists is, you can do a $ git remote -v. If you think this is there by some error, you can update it like so:

$ git remote set-url origin git@github.com:ppreyer/first_app.git

Laravel : Specified key was too long error

Laravel 5.4 or later  made a change to the default database character set, and it’s now utf8mb4 which includes support for storing emojis. This only affects new applications and as long as you are running MySQL v5.7.7 and higher you do not need to do anything.

For those running MariaDB or older versions of MySQL you may hit this error when trying to run migrations:

[Illuminate\Database\QueryException]
 SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table users add unique users_email_unique(email))

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

 

As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

 

use Illuminate\Support\Facades\Schema;

public function boot() {

Schema::defaultStringLength(191);

}
