我正在尝试hhvm-git从 AUR 安装软件包并收到错误。子模块之一存在错误。这个错误已经被修复，我想指定修订版包含子模块的修复。我怎样才能做到这一点？
在 PKGBUILD 中，我尝试按照Arch Wiki中的建议指定修订版（source数组中的行）：
"git+https://github.com/facebook/proxygen#7e37f926d922b55c85537057b57188dea9694c32"
结果：
-> Creating working copy of proxygen git repo...
remote: Counting objects: 6, done.
remote: Compressing objects: 100% (6/6), done.
remote: Total 6 (delta 4), reused 0 (delta 0)
Unpacking objects: 100% (6/6), done.
