Call to undefined method Symfony\Component\Process\ProcessUtils::escapeArgument()

[Phiter Fernandes]

I've upgraded my lumen installation to 5.6 and I'm getting this error:

In ServeCommand.php line 40:

Call to undefined method Symfony\Component\Process\ProcessUtils::escapeArgument()

I haven't tested the other commands, but apparently this function has been removed.
