看起来您已经在旧版本中安装了一些依赖项：
- Conclusion: remove zendframework/zend-filter 2.7.2
- Installation request for zendframework/zend-filter (locked at 2.7.2) -> satisfiable by zendframework/zend-filter[2.7.2].
- Installation request for zendframework/zend-inputfilter (locked at 2.7.6) -> satisfiable by zendframework/zend-inputfilter[2.7.6].
要安装zend-form，您必须更新相互矛盾的依赖项。
您也可以尝试composer require zendframework/zend-form zendframework/zend-filter ...也可以明确更新每个依赖关系，从而添加每个新的依赖项，直到解决。
另外，您可以使用以下选项之一：
--update-with-dependencies Allows inherited dependencies to be updated, except those that are root requirements.
--update-with-all-dependencies Allows all inherited dependencies to be updated, including those that are root requirements.
所以：
composer require --update-with-all-dependencies zendframework/zend-form --dev
这是更"刺激性"的选项，因为它还更新了词根依赖性，这可以说是更危险的，因为它们直接影响您的代码，而对于其他更新，理想情况下，您的库应确保它们可以与所选版本一起使用，并且您可以使用。不应该自己直接使用它们。
这可能会更新比您预期的更多依赖关系，并可能导致副作用。确保拥有清洁的GIT历史记录和工作测试套件，以确保更新不会破坏任何内容。您应该可以从输出或Composer.lock中的更改中看到哪些更新的依赖项。这也可以帮助识别用于使用这些依赖项的应用程序部分测试的热点。
