IDEA创建项目push到git上报错“Push rejected: Push to origin/master was rejected”

Push rejected: Push to origin/master was rejected

解决方案如下：

1.“Show in Explorer”切换到自己项目所在的目录，Git Bash Here

2.依次输入命令：

git pull

git pull origin master

#[ --allow-unrelated-histories]是告诉系统我允许合并不相关历史的内容
git pull origin master --allow-unrelated-histories

3.在idea中重新push自己的项目，搞定！！！
