我有个黑科技办法

参考 core.sshCommand If this variable is set, git fetch and git push will use the specified command instead of ssh when they need to connect to a remote system. The command is in the same form as the GIT_SSH_COMMAND environment variable and is overridden when the environment variable is set. 首先需要确认 git remote -v 是不是ssh连接 然后执行 git config --local --add core.sshCommand 'ssh -i /path/to/private' 之后就可以使用定制的私钥位置访问了

或者残暴点

GIT_SSH_COMMAND='ssh -i private_key_file' git pull
