我希望有人可以帮助我，因为我已经为此奋斗了好几天，并为此感到沮丧。我已经在运行Windows 10的全新笔记本电脑上设置了标准git客户端（来自git-scm.com），并正在Github.com上托管的存储库中。
最初，由于本地Windows OpenSSH客户端与git附带的捆绑的SSH客户端发生冲突，我在SSH配置中遇到了一些冲突。因此身份验证失败。通过设法根据Adam Ralph's suggestion显式设置全局sshCommand配置值，可以解决此问题。这使我摆脱了身份验证问题，并且能够很好地从GitHub进行克隆，获取和提取。但是，当我尝试推送时，我没有遇到以下错误。

我一直在搜索google和stackoverflow，并尝试了所有可以找到的解决方案：
http.postbuffer的值设置为500MB-1GB（尽管我的仓库没有大文件，只有少量的小型打字稿文件）git push命令，进行了一些健全性检查git filter-branch以清理仓库ssh -vv来打开更详细的日志记录。这样会将控制台日志记录更新为在下面阻止。在这一点上，我可以通过切换到HTTPS远程连接来取消能够实际执行的工作，但是在使用git的几年中，我从未遇到过使用SSH这样的问题。有没有人遇到过这样的事情？有什么明显的我想念的吗？

我已经设法通过按照Adam Ralph的建议显式设置全局sshCommand config值来解决。
是，但不是：首先尝试在CMD会话中使用Git，在该会话中您放置了简化的PATH，在该会话中，Git捆绑的openSSH将首先出现并被使用（OpenSSH_8.2p1，OpenSSL 1.1.1d 9月10日2019），而不是Windows中的旧版本
set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%
git config --gobal --unset core.sshCommand
cd C:\path\to\repo
git config --local --unset core.sshCommand
然后在该CMD会话中再试一次，以测试SSH问题是否仍然存在。

写入几个字节后，连接将关闭， 目标https://github.com/john-shaskin/polly-notes-reader 请尝试以下操作：
在Windows上运行git bash（请勿使用openssh，仅使用git bash），然后输入以下命令
git config --global http.postBuffer 524288000
git config --global ssh.postBuffer 524288000
使用简单的设置进行git push
git config --global push.default simple
将文件夹更改为要提交的存储库
cd /{driveletter}/{rootdir}/{repo}/{src}
cd /d/projects/repo/src <---- change accordingly.
现在尝试
git push
如果仍然出现错误，则需要启用GIT_TRACE_PACKET = true和GIT_TRACE = 2，再次将错误日志发布到此处，我将为您提供帮助。
