    - Root composer.json requires zendframework/zend-component-installer ^2.1.1 -> satisfiable by zendframework/zend-component-installer[2.1.1, 2.1.2].
    - zendframework/zend-component-installer[2.1.1, ..., 2.1.2] require composer-plugin-api ^1.0 -> found composer-plugin-api[2.6.0] but it does not match the constraint.
