git pull fatal

In first day for using git ,I met a problem:

Git Pull Failed，

fatal: refusing to merge unrelated histories

which means i cannt pull directly.

so i search for some materials.

now i copy the code below:

git pull origin master -–allow-unrelated-histories

git add .

git commit

then we are in VIM.

come to input：按i键

exit from output：Esc键 —— Shift+;键 —— wq!(保存并退出)或q!(不保存退出) —— Enter

then type:

git push origin master

successfully we solve the problems!
