Requirements not satisfied

I think you need to update the composer.lock file first (adding 'composer update --lock' right after composer.json has been updated successfully) before updating the dependencies because I encounter an error that tells me to make sure my symfony/process specific versions are already correct. I think this error is because of the composer.lock file not being updated right after the composer.json has been updated successfully. Please tell me if the mistake is on me, because all I did was following your README instruction but still encounter those errors. Thanks.
