Installation failed, reverting ./composer.json to its original content.

Answer 1

您似乎已经在旧版本中安装了某些依赖项：

- 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，您将必须更新冲突的依赖项。

您也可以尝试composer require zendframework/zend-form zendframework/zend-filter ...来显式更新每个依赖项，添加即将出现的每个新依赖项，直到解决为止。

或者，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.

例如：

composer require --update-with-all-dependencies zendframework/zend-form --dev

这是更“激进”的选项，因为它还会更新根依赖关系，因为根依赖关系会直接影响您的代码，因此可能会更加危险，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，并且不应该自己直接使用它们。

这可能会更新比您预期更多的依赖关系，并可能导致副作用。确保具有干净的git历史记录和有效的测试套件，以确保更新不会破坏任何内容。您应该能够从输出或composer.lock中的更改中看到哪些依赖项已更新。这也可以帮助确定热点，以测试使用这些依赖项的应用程序部分。
