我正在尝试从 git 源代码构建 Qt5 的修订版 5.9，但更新子模块失败：
git clone https://github.com/qt/qt5.git
cd qt5
git checkout 5.9
./init-repository
...
... lots of submodules being updated successfully
...
fatal: Needed a single revision
Unable to find current revision in submodule path 'qtnetworkauth'
git submodule update --force --no-fetch exited with status 256 at ./init-repository line 198.

所以看起来qtnetworkauth配置错误，但我不知道如何解决。我试图通过删除.gitmodules、qtdoc和文件夹本身中的引用来删除qtnetworkauth模块，但随后其他模块失败。
奇怪的是 - 当我在删除并添加对qtnetworkauth的引用后运行./init-repository -f时，我可以看到它正在被签出，但子模块文件夹仍然是空的：
...

我能做错什么？或者，如果这是一个Qt错误 - 我该如何解决它？
在实际获取所有存储库之前，您正在更改分支。这可能会破坏./init-repository脚本中的某些内容。
我已经检查了这个序列是否有效：
git clone git://code.qt.io/qt/qt5.git
cd qt5/
./init-repository
git checkout 5.9
git submodule update
