Problem
During composer installation, you see the following error message(s):
Example:
Command "update" failed: Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - tnw/module-stripe 2.1.11 requires stripe/stripe-php ~5.8.0 -> satisfiable by stripe/stripe-php[v5.8.0] but these conflict with your requirements or minimum-stability. - tnw/module-stripe 2.1.11 requires stripe/stripe-php ~5.8.0 -> satisfiable by stripe/stripe-php[v5.8.0] but these conflict with your requirements or minimum-stability. - Installation request for tnw/module-stripe 2.1.11 -> satisfiable by tnw/module-stripe[2.1.11].
Solution
This most likely means your Magento stability requirement does not match the requirement of the extension or the extension dependencies. Running the following command usually fixes the issue
*nix command
composer config minimum-stability dev
