如何不使用用户名和密码进行git的push pull操作(Stack Overflow转载）

If you have configured SSH key to your Github account and are still getting the password prompt, make sure your repo URL is in the form

git@github.com:username/reponame.git

as opposed to

https://github.com/username/reponame.git

To see your repo URL, run:

git remote show origin

You can change the URL with:

git remote set-url origin git@github.com:username/reponame.git

之后再次运行bundle install可解决
