Conflict regarding nikic/php-parser version (Symfony 4)

[martin-juul]

I tried to start a new project with symfony 4, doctrine and maker. But php-di requires a version of nikic/php-parser at ^2.0|^3.0 - would it be possible to update the dependency requirements?

Error log:

composer require php-di/symfony-bridge

Using version ^3.0 for php-di/symfony-bridge
./composer.json has been updated
