更新 git 子模块

Question

在尝试更新 git 子模块时，我看到以下错误：

Submodule 'paa' (https://github.com/microsoftgraph/paa.git) registered for path 'paa'
Cloning into 'D:/a/1/s/paa'...
git: 'credential-manager-core' is not a git command. See 'git --help'.
fatal: could not read Username for 'https://github.com': terminal prompts disabled
fatal: clone of 'https://github.com/microsoftgraph/paa.git' into submodule path 'D:/a/1/s/paa' failed
Failed to clone 'paa'. Retry scheduled
Cloning into 'D:/a/1/s/paa'...
git: 'credential-manager-core' is not a git command. See 'git --help'.
fatal: could not read Username for 'https://github.com': terminal prompts disabled
fatal: clone of 'https://github.com/microsoftgraph/paa.git' into submodule path 'D:/a/1/s/paa' failed
Failed to clone 'paa' a second time, aborting
##[error]Git submodule update failed with exit code: 1

我引用了Fatal Error when updating submodule using GIT堆栈溢出帖子，.gitmodules 已经有以下内容：

[submodule "paa"]
    path = paa
    url = https://github.com/microsoftgraph/paa.git

更新：

根据以下答案，我添加了一个路径，如下所示：

C:\Program Files\Git\bin
C:\Program Files\Git\cmd
C:\Program Files\Git\usr\bin
C:\Program Files\Git\mingw64\bin
C:\Program Files\Git\mingw64\libexec\git-core

我仍然看到同样的错误。我尝试将 .gitmodules 中的内容更新为以下内容：

[submodule "paa"]
    path = paa
    url = https://<username>:<password>@github.com/microsoftgraph/paa.git

我看到了这个错误：

Submodule 'paa' (https://<username>:<password>@github.com/microsoftgraph/paa.git) registered for path 'paa'
Cloning into 'D:/a/1/s/paa'...
fatal: unable to access 'https://<username>:<password>@github.com/microsoftgraph/paa.git/': Could not resolve host: <username>:<password>@github.com
fatal: clone of 'https://<username>:<password>@github.com/microsoftgraph/paa.git' into submodule path 'D:/a/1/s/paa' failed

对于我最近 (2.29) 的所有 Windows Git 安装，我必须将 %GH%\mingw64\libexec\git-core 添加到我的 PATH（GH 是安装 Git 的路径）。
以VonC/setupsenv commit f1a1dcd为例：

set PATH=%GH%\bin;%GH%\cmd;%GH%\usr\bin;
set PATH=%GH%\mingw64\bin;%GH%\mingw64\libexec\git-core;%PATH%
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

这样，GCM (Microsoft Git-Credential-Manager-Core 变得可用，并且不再出现错误消息。
