Git Giving "fetch first" error when trying to push

Question

I am having my first introduction to git through a class I am taking. I have a number of files in a directory on my computer and am able to stage and commit them without a problem. However, when I try to push files to my github repository, I keep on getting this message:

Pushing to https://github.com/BigMeanCat/CMDA
To https://github.com/BigMeanCat/CMDA
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/BigMeanCat/CMDA'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Can anybody help me out with what this means and how to fix it? I've seen a few people with similar problems online, but I am BRAND NEW to git and not familiar enough with git's command line language yet. I'm a little hesitant to take certain suggestions, as I don't know whether it will solve the problem or make it worse.

Thanks!

Answer 1

I have been taken same error, then I solved this topic with used "--force" command. Briefly, write this command;

git push origin master --force

Attention: Probably, you tried to do push your codes over and over again before , that's why you took this error.My solution overwrite forcefully with your changeset. By this method your repository may cause mismatch other people's. But If you work alone (not like a group working), so you can use easily "--force" as I mentioned above.
