无法使用git lfs克隆存储库

问题描述

我的回购使用git lfs。对于新鲜的克隆，我运行：

  git lfs install 
 git clone https://example.com/repo .git 
  

克隆到达开始下载lfs文件的位置，到达某个文件，然后失败。每次我尝试克隆时，失败的文件都不相同。

以下是输出：

 克隆进入'回购'...

如果我尝试 git lfs pull 在这一点上，一切正常。

任何想法可能会导致此失败下载lfs f我有类似的问题，并有。当错误得到解决的时候，这个解决方法帮助了我，在那里你跳过了它失败的过滤器。

  //跳过涂抹 - 我们稍后会以更快的批次下载二进制文件
 git lfs install --skip-smudge 
 
 //做git clone here 
 git clone ... 
 
 //获取新克隆中的所有二进制文件
 git lfs pull 
 
 //恢复污迹
 git lfs install --force

My repo uses git lfs. For a fresh clone, I ran:

git lfs install
git clone https://example.com/repo.git

The clone gets to the point where it starts downloading lfs files, gets to some file and then fails. The file at which it fails is different each time I attempt to clone. Very occasionally it succeeds.

Here is the output:

You can inspect what was checked out with 'git status'
and retry the checkout with 'git checkout -f HEAD'

The lfs logs say:

If I try git lfs pull at this point, everything works fine.

Any idea what could be causing this failure to download the lfs files?

解决方案

I had the similar issue and there was already a bug reported with git lfs. While the bug was being resolved, this workaround helped me, where you skip the filter where it was failing.

// Skip smudge - We'll download binary files later in a faster batch
git lfs install --skip-smudge

// Do git clone here
git clone ...

// Fetch all the binary files in the new clone
git lfs pull

// Reinstate smudge
git lfs install --force
