get "FileExistsError: [WinError 183]" when repo sync

[Awille]

I use "https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/" to download aosp, firsr i download the latest code in tar:

curl -OC - https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar # download latest code tar
tar xf aosp-latest.tar
cd AOSP   
# it just has a .repo file when unzip.
repo sync 

I met this error when repo sync:

delete current vertion of git and.. re install git using latest version.
also take care about Symbolic link option when setup wizard almost last selection page.
after install git. execute git bash under administrator's previlege.
