这是我终端上的错误：
Authentication failed for 'https://bitbucket.org/railstutorial/sample_app_4th_ed.git/'
这就是我所做的：
git remote add origin ssh://git@bitbucket.org/kboygitgit/sample_app.git
git push -u origin master
然后它要求我的用户名和密码
然后出现错误
remote: Unauthorized
fatal: Authentication failed for 'https://bitbucket.org/railstutorial/sample_app_4th_ed.git/'
