我不能在 contao 项目中要求以下包。

$ php composer.phar require -v con4gis/con4gis_forum
Using version ^1.7 for con4gis/con4gis_forum
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Dependency resolution completed in 0.026 seconds
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Conclusion: don't install con4gis/con4gis_forum v1.7.1
    - Installation request for con4gis/con4gis_forum ^1.7 -> satisfiable by con4gis/con4gis_forum[v1.7.0, v1.7.1].
    - con4gis/con4gis_forum v1.7.0 requires con4gis/con4gis_core ~1.7 -> satisfiable by con4gis/con4gis_core[v1.7.0, v1.7.1].
    - con4gis/con4gis_core v1.7.0 requires menatwork/contao-multicolumnwizard 3.3.8 -> satisfiable by menatwork/contao-multicolumnwizard[3.3.8].
    - con4gis/con4gis_core v1.7.1 requires menatwork/contao-multicolumnwizard 3.3.8 -> satisfiable by menatwork/contao-multicolumnwizard[3.3.8].
    - Conclusion: don't install menatwork/contao-multicolumnwizard 3.3.8


$ php composer.phar why-not menatwork/contao-multicolumnwizard
contao-legacy/semantic_html5      1.1.7.9014    requires  contao-legacy/multicolumnwizard (>=3.0.0,<4.0.0-dev)  
metamodels/attribute_alias        2.0.0-alpha2  requires  menatwork/contao-multicolumnwizard (~3.3)             
metamodels/core                   2.0.0-alpha9  requires  menatwork/contao-multicolumnwizard (~3.3)             
psi/news4ward                     2.2.3         requires  menatwork/contao-multicolumnwizard (~3)               
terminal42/contao-changelanguage  3.1.0         requires  menatwork/contao-multicolumnwizard (^3.3)

我检查了为什么不打印的所有要求，并且 3.3.8 已经是绿色的，即满足https://semver.mwl.be/#?package=menatwork%2Fcontao-multicolumnwizard&version=%5E3.3&minimum-stability=stable

到底是怎么回事？

删除composer.lock也没有帮助。

Composer 版本是最新的稳定版。

将您复制composer.json到本地文件、artifact从中删除存储库并运行composer install会导致legacy/survey_ce 3.0.2.9003找不到消息。但是，3.0.2.9005据报道是可用的，所以我继续。

再次运行composer install会产生一组可解析的依赖项。再次运行您的composer require命令会导致您收到相同的错误消息。我想我现在在同一个地方。

运行composer show以列出所有已安装的包显示有问题的包已安装在版本 3.3.10 中。

menatwork/contao-multicolumnwizard               3.3.10             MultiColumWizard for Contao OpenSource CMS

这就解释了为什么无法安装依赖项，因为 Composer 通常不会对已安装的包进行降级。然而，它给出的提示并没有真正解释发生了什么。

正如我在评论中提到的，您应该立即尝试彻底检查您的依赖项：

  1. 您依赖于固定版本。检查您是否可以放宽版本号以允许兼容更新。如果库作者声明他们支持语义版本控制，这是最简单的，如果他们声明他们明确不支持它，如果他们还声明如何获取补丁，这也很容易。
  2. 您取决于dev-master版本。取决于分支会在某些时候破坏你的项目！检查您正在使用的库是否已发布标记版本。检查您当前引用的最接近的版本。将您的依赖项从该版本更改dev-master（包括兼容的更新，如第一点所述）并查看您的项目是否仍然有效。
  3. 您还依赖于废弃的版本。您应该将依赖项升级到引用的包 - 但是这绝不保证是一个轻松的转换，可能需要进行一些更改。但这将有助于减少所涉及的软件包数量，因为似乎许多contao-legacy库都以 . 的形式重新发布menatwork，并且确实得到了更新。而且这些库应该是可以切换的。
