What is your install command? Are you upgrading dependencies?

What is your install command? Are you upgrading dependencies?

I am planning to use your project in Laravel, but there was a dependency conflict when installing the php-pm/httpkernel-adapter package.
I first introduced the composer require php-pm / php-pm package in the project, and then reported an error when introducing composer require php-pm / httpkernel-adapter

Ok, but could you answer the question? What is your (verbatim) install command? Viele Grüße, Andreas

I don't understand what your mean by the installation command, do you mean composer?
Let me talk about my installation process,
1.composer create-project laravel/laravel lv-pm
2.composer require php-pm/php-pm
3.composer require php-pm/httpkernel-adapter
Then I got an error.

Exactly. Could you please try as suggested and run composer with --update-with-dependencies?

[wenber-yu]

@andig I think I found the cause of the dependency conflict, but I have n’t determined which package caused it. Using the --update-with-dependencies option you mentioned in the current directory did not work. But I ’m working on a new laravel In the new pm project, the package was successfully introduced. So it should be the problem caused by the introduction of other packages. I will feedback after I am sure, thank you for your reply.

You could also try --update-with-all-dependencies, symfony/error-handler ^5 is definitely allowed.

Yes, I am already doing this. Thanks for your suggestions.

Did you solve this or could provide steps to reproduce from the point of installing Laravel on?
