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

Answer 1

您似乎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].

为了安装 zend-form，您必须更新冲突的依赖项。

您也可以尝试 composer require zendframework/zend-form zendframework/zend-filter ... 显式更新每个依赖项，添加每个出现的新依赖项，直到它被解决。

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

这是更多 "drastic" 选项，因为它还会更新根依赖项，这可以说更危险，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选择的版本，你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项，并可能导致副作用。确保有一个干净的 git 历史记录和一个有效的测试套件，以确保更新没有破坏任何东西。您应该能够从输出或 composer.lock 中的更改中看到更新了哪些依赖项。这还可以帮助识别热点，以测试应用程序中使用这些依赖项的部分。
