当尝试使用Git进行拉动或推送时，这种情况才刚刚开始。最后我在几天前使用它时工作正常，我无法想到我对我的系统所做的任何会影响它的事情。如果我尝试SSH到GitHub或BitBucket，我会得到相同的结果。我已经完成了一些谷歌搜索，但我找不到任何相似的内容，而且我很难知道在没有错误消息的情况下搜索什么内容。我已经尝试使用随自制程序安装的openssh版本，我将其更新到最新版本，以及我的Mac OS附带的版本。我尝试卸载自制软件，以确保没有发生冲突。没有任何帮助。
在我放弃并重新安装整个操作系统之前，我们将非常感谢您的帮助。
更新：我找到了this issue，并尝试unset SSH_AUTH_SOCK似乎解决了问题，提示我的ssh-agent出了问题。 （我确实尝试重启我的机器）
更新2：解决方案！我查看了控制台应用程序，发现错误消息说未找到文件/ usr / local / bin / ssh-agent（这是在我卸载了自制的openssh版本后，所以使用了系统一个）
在/ usr / bin / ssh-agent中添加符号链接修复了所有内容。
我不明白自制版本出了什么问题。这确实在usr / local / bin中添加了ssh-agent的链接，并且我在启动时没有收到错误消息，而是在我尝试在终端中使用它时，ssh-agent似乎崩溃了。 / p>
在控制台中我得到了
Service exited with abnormal code: 1
然后服务不断尝试重新启动并失败
Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
似乎自制软件和OS X openssh don't play nice together。 仍然不明白为什么直到现在才开始工作。
我在OSX 10.10.5（约塞米蒂）上。
以下是自制软件版本的-vvv调试输出：
