Phenomenon

Right after you've committed ur local change, you're gonna execute the operation git push from the right-click context menu in Pycharm, but you got such error pop-up of Push failed: Failed with error: Could not read from remote repository.

Go to download&install the windows version of OpenSSH here.
Go to the setting of Pycharm, and Version Control--> Git , and then, In the SSH executable drop-down, choose Native.
Generate the ssh key-pair on Windows using the command like ssh-keygen -C 'Win10', if you don't encounter with this error of Saving key "/home/sudosu/.ssh/id_rsa" failed: No such file or directory(obviously, this path style doesn't belong to windows, I directly gave up to find the solution), great!
But if you're not very lucky like me, what I did is to directly copy the private ssh-key from my dev Linux-box into this path of C:\Users\Sharp\.ssh(do not forget to replace the username with yours and check the corresponding public key whether it's in your Github setting.)
