Unable to Install Library with Composer due to guzzlehttp/psr7 conflict

[Nick Harris]

I run the command "composer require googleads/googleads-php-lib" and this is what I get:

Using version ^25.0 for googleads/googleads-php-lib
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

    - Installation request for guzzlehttp/psr7 (locked at 1.3.1) -> satisfiable by guzzlehttp/psr7[1.3.1].

Installation failed, reverting ./composer.json to its original content.

Any ideas how to get it to work?

Hi Nick,

Could you confirm if you have followed this guide in setting up your PHP client library? If yes, and if the issue persists, you may get in touch directly with the library owner through here. Hope this helps.

Thanks and regards,

Peter
