Installing Microsoft Graph SDK via Composer results in PHP-PSR4 issues-CodePudding

Attempting to install the Microsoft Graph SDK is resulting in strange behaviour.

When running composer install microsoft/microsoft-graph I see this output:

Post installation, my composer.json contains "microsoft/microsoft-graph": "^1.74",

I cannot find any known issues around this? Any help appreciated.

CodePudding user response：

delete composer.lock and vendor and install again by running composer install

if still not working, then either there is some issues of dependancies or your composer version is causing issues with the package you trying to install.

what's your composer version?

you you can play around with composer version using the following following;

composer self-update // to update to latest version

composer self-update --rollback // roll back to previous version if you have one

composer self-update 1.1.1 // install specific version

after changing composer version, delete vendon and lock file and run composer install again

EDIT

its actually a known issue with the latest version of the package https://github.com/microsoftgraph/msgraph-sdk-php/issues/791

you should try older version maybe
