I tried with this: composer require s9e/flarum-ext-mediaembed:0.1.0 (The version that I have of Flarum), but I tried too with the command that you say: composer require s9e/flarum-ext-mediaembed:*, and the error that I get is this:
-bash-4.2$ composer require s9e/flarum-ext-mediaembed:*
./composer.json has been updated
