Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires wp-cli/wp-cli-tests ^5 -> satisfiable by wp-cli/wp-cli-tests[v5.0.0, ..., 5.1.x-dev]. - wp-cli/wp-cli[dev-copilot/display-memory-limit-wp-cli, ..., dev-autocomplete-urls, v2.12.0, ..., 2.13.x-dev] require wp-cli/php-cli-tools ~0.12.4 -> satisfiable by wp-cli/php-cli-tools[v0.12.4, v0.12.5, v0.12.6, v0.12.7] from composer repo (https://repo.packagist.org) but wp-cli/php-cli-tools 0.13.x-dev is the root package and cannot be modified. See https://getcomposer.org/dep-on-root for details and assistance. - wp-cli/wp-cli-tests[v5.0.0, ..., 5.1.x-dev] require wp-cli/wp-cli ^2.12 -> satisfiable by wp-cli/wp-cli[v2.12.0, 2.13.x-dev (alias of dev-main)]. - wp-cli/wp-cli 2.13.x-dev is an alias of wp-cli/wp-cli dev-main and thus requires it to be installed too.
