Message 'src refspec master does not match any' when pushing commits in Git

Question

I clone my repository with:

git clone ssh://xxxxx/xx.git 

But after I change some files and add and commit them,

Answer 1

Missing or skipping git add . or git commit may cause this error:

git push -u origin master
Username for 'https://github.com': yourusername
Password for 'https://yourusername@github.com': 
error: src refspec master does not match any.
error: failed to push some refs to 'https://github.com/yourusername/foobar.git'

To fix it, reinitialize and follow the proper sequence:

git init
git add .
git commit -m 'message'
git *create remote
git push -u origin master
