为什么git bash不允许我推送到远程仓库？

Question

I am a new developer and just began learning git and github. I have two repos on github, one to show the code for a project and then I made another so I could host the page to show off the project with github pages. I made a small change and pushed the commit to my original remote repo, and then tried to push the commit to the other repo and I keep getting this error:

Owner@MICHAEL-WORK-PC MINGW64 ~/Desktop/Coding/Dual N-Back Game Project (master|MERGING)
$ git push github master
To https://github.com/michaelacook/michaelacook.github.io
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/michaelacook/michaelacook.github.io'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

I have no idea why this is happening or how to fix it, I'm too new to git. Any suggestions? Thanks.

You must pull before you push.

You have changes in your remote repository which does not exist in your local and you must pull them and perform a merge.

# pull changes
git pull origin master

# if you have a conflicts resolve them and ad your files
git add .

# commit your resolution
git commit 


# now you can push your changes
git push origin master
