Just run composer install - it will make your vendor directory reflect dependencies in composer lock file    In other words - it will delete any vendor which is missing in composer lock   Please update the composer itself before running this

In fact  it is very easy   composer update   will do all this for you  but it will also update the other packages   To remove a package without updating the others  specifiy that package in the command  for instance   composer update monolog monolog   will remove the monolog monolog package   Nevertheless  there may remain some empty folders or files that cannot be removed automatically  and that have to be removed manually

The right way to do this is   composer remove jenssegers mongodb --update-with-dependencies   I must admit the flag here is not quite obvious as to what it will do   Update  composer remove jenssegers mongodb   As of v1 0 0-beta2 --update-with-dependencies is the default and is no longer required
