TortoiseGit disconnected no supported authentication methods available

安装好小乌龟git后，用小乌龟的pull 从github上拉取项目，遇到错误：

disconnected no supported authentication methods available(server sent: publickey) 

或者是 git did not exit cleanly (exit code 1)

亦或者是 git did not exit cleanly (exit code 128)

因为TortoiseGit和Git的冲突。 改正如下：
设置TortoiseGit > Settings > Network > SSH Client为C:\Program Files\Git\usr\bin\ssh.exe
