Difficulty installing

I tried the suggested install command:
composer require 'drupal/cloudflare_node_cc:^1.0'
and got errors, so I then tried specifying the latest version:
composer require 'drupal/cloudflare_node_cc:^1.0.2'

I'm getting these errors and don't understand what I need to do:
- cloudflare/sdk[1.1.0, ..., 1.1.6] require guzzlehttp/guzzle ^6.2.2 -> found guzzlehttp/guzzle[6.2.2, ..., 6.5.8] but the package is fixed to 7.9.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- cloudflare/sdk[1.1.7, ..., 1.4.0] require psr/http-message ~1.0 -> found psr/http-message[1.0, 1.0.1, 1.1] but the package is fixed to 2.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

thanks for your help
