我正在尝试将我在本地目录中正确创建的文件“HelloWorlds.md”推送到GitHub存储库。我在MacOS High Sierra上使用https，尽管我努力在Git中缓存我的Github密码，但我一直收到“无效的用户名和密码”错误。以下是我的代码：
ChrisC-MacBook-Pro:datasciencecoursera chriscalitz$ ls
HelloWorld.md README.md https:
ChrisC-MacBook-Pro:datasciencecoursera chriscalitz$ rm https:
rm: https:: is a directory
ChrisC-MacBook-Pro:datasciencecoursera chriscalitz$ git push

成功将.md文件推送到Github存储库需要什么代码？谢谢！
