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

Answer 1

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].

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，添加在此过程中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“激烈”的选项，因为它还更新根依赖项，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，您的库应该确保它们可以使用所选的版本，并且您不应该自己直接使用它们。

这可能会更新比您预期的更多的依赖项，并可能导致副作用。确保有一个干净的git历史记录和一个工作测试套件，以确保更新没有破坏任何东西。您应该能够从输出或composer.lock中的更改中看到哪些依赖项被更新。这还可以帮助识别用于测试应用程序中使用这些依赖项的部分的热点。
