FOR EXAMPLE: 
I have 3 commits in history:
commit 1: #3333 zzzzzz
commit 2: #2222 yyyyyy
commit 3: #1111 xxxxxx
NOW, I want to squash last 2 commits

Step 1:

$ git reset --hard HEAD~2

then the output like this:

HEAD 现在位于 4cf49a1 #255 斗金绿色平台开发者列表可以按照选择拓展人员查看对应开发者列表

Step 2:

$ git merge --squash HEAD@{1}

then the output like this:

Step 4:

$ git push

OUTPUT:

To [email protected]:xxxx/bbbb.git
 ! [rejected]        master -> master (non-fast-forward)
error: 无法推送一些引用到 '[email protected]:xxxx/bbbb.git'
提示：更新被拒绝，因为您当前分支的最新提交落后于其对应的远程分支。
提示：再次推送前，先与远程变更合并（如 'git pull'）。详见
提示：'git push --help' 中的 'Note about fast-forwards' 小节。

if push get errors, you need to force push:

$ git push origin +master
