.gitmodules

[submodule "libraries/stb"]
    path = libraries/stb
    url = https://github.com/nothings/stb.git
    branch = master
[submodule "libraries/harfbuzz"]
    path = libraries/harfbuzz
    url = https://github.com/harfbuzz/harfbuzz.git
    branch = master
[submodule "libraries/shaderc"]
    path = libraries/shaderc
    url = https://github.com/google/shaderc.git
    branch = master
[submodule "libraries/freetype2"]
    path = libraries/freetype2
    url = https://github.com/aseprite/freetype2.git
    branch = master
[submodule "libraries/VulkanMemoryAllocator"]
    path = libraries/VulkanMemoryAllocator
    url = https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator.git
    branch = master
[submodule "libraries/googletest"]
    path = libraries/googletest
    url = https://github.com/google/googletest.git
    branch = master
[submodule "libraries/Eigen"]
    path = libraries/Eigen
    url = https://gitlab.com/libeigen/eigen.git
    branch = master
[submodule "libraries/benchmark"]
    path = libraries/benchmark
    url = https://github.com/google/benchmark.git
[submodule "libraries/rapidcheck"]
    path = libraries/rapidcheck
    url = https://github.com/emil-e/rapidcheck.git
    branch = master
[submodule "libraries/magic_get"]
    path = libraries/magic_get
    url = https://github.com/apolukhin/magic_get.git
    branch = master

命令和输出：

git pull --recurse-submodules=true

这曾经在大约 6 个月前起作用

【问题讨论】：

您未能获取的存储库有什么变化吗？也许他们的网址？也许分支主不存在了？
据我所知。所有这些都是相当流行的库，由大型组织维护。如果他们要打破依赖关系，我会感到震惊

标签： linux git github gitlab git-submodules

【解决方案1】：

以防万一，确保所有子模块都已初始化：

git submodule update --init --recursive

然后，再次尝试pull --recurse-submodules=true。

不知何故，activating the traces 改善了情况：

git -c trace2.eventTarget=1 pull --recurse-submodules=true

【讨论】：

尝试此方法后错误仍然存在
@Makogan 您能否检查缺少的子模块引用了哪个 SHA1（git submodule status 或查看 stackoverflow.com/q/20655073/6309）？目标是检查远程存储库中是否存在该引用。
该命令似乎有效，它提取了所有子模块，即带有事件目标的子模块
@Makogan git -c trace2.eventTarget=1 pull --recurse-submodules=true?
@Makogan 奇怪！我已经相应地编辑了答案。
