我经常在项目中运行composer update，然后检查更新了哪些依赖项。但今天我发现了一个奇怪的输出：
Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 0 installs, 2 updates, 0 removals
- Updating phpdocumentor/type-resolver (0.4.0 => 0.3.0): Downloading (100%)
- Updating phpdocumentor/reflection-docblock (3.2.0 => 3.2.1): Downloading (100%)
Writing lock file
你可以看到phpdocumentor / type-resolver包从0.4.0降级到0.3.0，尽管命令是update。
是正常还是错误或其他什么？
答案 0 :(得分：0)
我似乎找到了答案。它在此提交中：Downgrade phpdocumentor/type-resolver to 0.3
In order to restore a bc break made in 3.2.0 I downgraded the
type-resolver. This makes the version less compatible with php 7.1
But will help our users to upgrade.
确实phpdocumentor / type-resolver是phpdocumentor / reflection-docblock的依赖项，其维护者故意降级类型解析器。所以一切都很正常。而且它不是作曲家的错误。这是我第一次看到这样的行为，这就是为什么我发现它很奇怪。
