Composer php 无法解决编写器要求

我正在尝试更新我的composer依赖项，composer无法解决我的需求。我尝试过更新rezzza/formulate和hoa/math，但总是出现以下错误：

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- rezzza/formulate v1.0.2 requires hoa/math dev-master -> satisfiable by hoa/math[dev-master].
- rezzza/formulate v1.0.2 requires hoa/math dev-master -> satisfiable by hoa/math[dev-master].
- Removal request for hoa/math == 9999999-dev
- Installation request for rezzza/formulate == 1.0.2.0 -> satisfiable by rezzza/formulate[v1.0.2].

这是我的作曲家配置：

似乎是搬家的要求把我绊倒了，但我甚至不知道这意味着什么。我还看到了

rezza/format

库的两种不同版本格式：1.0.2和1.0.2.0——也许这也是一个问题？

我运行了

composer更新rezza/format

，解决了我的安装需求问题
