IDEA git报错Push to origin/master was rejected

IDEA git报错"Push to origin/master was rejected"是因为在将项目上传到已存在文件的GitHub仓库时出现的错误。为了解决这个问题，你可以按照以下步骤进行操作：

1. 首先，在项目根文件夹中右击，选择"Git Bash Here"打开Git命令行工具。

2. 在Git命令行中，输入以下指令来解决报错：
git pull origin master --allow-unrelated-histories
这个指令会将远程仓库（GitHub）的最新代码合并到本地代码中，解决代码冲突。

3. 接下来，输入以下指令来将本地代码强制推送到远程仓库：
git push -u origin master -f
这个指令会强制推送本地代码到GitHub仓库，并更新远程仓库的代码。

通过以上步骤，你应该能够成功解决IDEA git报错"Push to origin/master was rejected"的问题。这样你就能够将项目上传到已存在文件的GitHub仓库了。<span class="em">1</span><span class="em">2</span>
