You’ll need to upgrade zendframework/zend-view first: [https://github.com/zendframework/zend-mvc-plugin-flashmessenger/blob/1.1.0/composer.json#L23](https://github.com/zendframework/zend-mvc-plugin-flashmessenger/blob/1.1.0/composer.json#L23)

I found by myslef…
the zend-view module I used was 2.8.1, but required is 2.10 !!!
after update ( c:\> composer update zendframework/zend-view), installation is ok !!!
now i use zend-view module 2.10.0
and the **composer require zendframework/zend-mvc-plugin-flashmessenger** command worked like a charm !
maybe this can help someone…
