致命:目标路径'opencv_contrib'已经存在，并且不是空目录 [英] Fatal: destination path 'opencv_contrib' already exists and is not an empty directory

问题描述

所以我尝试使用以下命令获取opencv_contrib:

So I tried to get opencv_contrib using :

$ git clone https://github.com/Itseez/opencv_contrib

哪个给了我以下错误:

致命:目标路径'opencv_contrib'已经存在，并且不是空目录.

fatal: destination path 'opencv_contrib' already exists and is not an empty directory.

我试图检查目录内容:

$ ls -a

$ ls -a

这就是我得到的:

对所有这些都是新手，我真的无法理解哪里出了问题以及需要做什么.主要是我需要知道如何使所需目录为空，以便继续安装.

Being new to all this, I really am unable to understand what's wrong and what needs to be done. Mainly I need to know how do I make the required directory empty so I can continue with the installation.

推荐答案

检查opencv_contrib是否已经是Git仓库:

Check if opencv_contrib is already a Git repo:

cd opencv_contrib
git status

如果是，则git pull(假设它仍在master上)应该将其更新.

If it is, a git pull (assuming it's still on master) should bring it up-to-date.

如果它不是Git仓库，并且您确定不需要它，只需删除目录并重试:

If it's not a Git repo, and you're sure you don't need what's in it, just remove the directory and try again:

cd ..
rm -rf opencv_contrib/
