在Windows上git：“错误：稀疏结帐在工作目录上没有条目” [英] On Windows git: “error: Sparse checkout leaves no entry on the working directory”

问题描述

我有错误：

 错误：稀疏结帐在工作目录中没有条目
  

当试图在git上设置一个稀疏结帐窗口时。在研究这个问题后，我已经回答了我自己的问题，并在网上发现了完整的答案。

在你想要源代码的文件夹中，使用git-bash提示NOT powershell （尽管见下面的编辑）：

  git clone -n​​< repo> <局部-目录名称> 
 cd< local-directory-name> 
 git config core.sparsecheckout true 
 echo some / sub-folder / you / want>> .git / info / sparse-checkout 
 git checkout< branch-name> 
  

完整说明

稀疏结帐可让您处理存储库的一个子集。这是值得的努力设置稀疏签出大型仓库，一切都快得多！

我努力在Windows上设置它得到很多错误：稀疏结帐在工作目录上不留下任何条目。经过一番研究，我发现以下步骤非常简单，对我来说一直有很好的结果 - YMMV。

最重要的一点是 - 不要使用POWERSHELL / CMD进行这些步骤 - 使用git bash提示符。这是因为否则echo命令会生成一个带有BOM标记的UNICODE文件。这个文件必须是ANSI格式的文件，UNIX风格的行结尾才能让git正确解析它。这是导致错误：稀疏结帐在工作目录上没有条目错误的最可能原因。

1. 假设文件夹名称为src执行以下操作，这将抓取整个回购（仍然需要），但重要的是不会执行结帐，并且正确设置原点远程和分支跟踪。

     git clone -n​​< your repository> src 
     




2. 你应该有一个相当空的src文件夹（它将隐藏.git文件夹）。现在运行以下。这会更新本地git配置以启用稀疏检出，并在.git / info隐藏文件夹中创建一个文件，该文件将列出您在执行稀疏检出时要包括的所有文件夹。这可以稍后编辑以添加其他文件夹。 重要：确保在下面使用git bash提示符，并使用支持unix行结束约定的编辑器，并在编辑稀疏检出文件时另存为ANSI，否则您可能会收到error：稀疏结账不会在工作目录中出现错误错误。 <您要签出的路径> 可能如下所示： path / to / subfolder - 注意缺少

     cd src 
    git config core.sparsecheckout true 
    echo<路径您要结帐> >> .git / info / sparse-checkout 
     




3. 现在您已准备好结帐。这应该只填充稀疏检出文件夹。如果没有，请仔细检查以上所有内容的拼写！

     git checkout< branch-name> 
     

编辑 - Powershell中的回声

我最近发现powershell中的echo是写输出的synomym。可以通过将echo输出到 out-file 命令来获取ASCII输出，该命令允许您指定编码。因此，这将从Powershell工作，并提供正确的文件内容：

  echo some / sub / folder / you / want | out-file -encoding ascii .git / info / sparse-checkout 
  

I had the error:

"error: Sparse checkout leaves no entry on the working directory"

when trying to set up a sparse checkout in git on windows. I've answered my own question after researching the issue and finding the full answer spread out across the web.

解决方案

tl;dr

From the folder in which you want the source to live, using a git-bash prompt NOT powershell (although see my edit below):

git clone –n <repo> <local-directory-name>
cd <local-directory-name>
git config core.sparsecheckout true
echo some/sub-folder/you/want >> .git/info/sparse-checkout
git checkout <branch-name>

Full explanation

Sparse checkouts enable you to work on a subset of the repository. It’s worth the effort to set up sparse checkouts on large repositories, everything is much faster!

I struggled with setting it up on windows getting a lot of "error: Sparse checkout leaves no entry on the working directory". After a bit of research, I found the following steps were minimal and had consistently good results for me – YMMV.

The most important point is this – DO NOT USE POWERSHELL/CMD FOR THESE STEPS – use a git bash prompt. This is because otherwise the echo command produces a UNICODE file with a BOM marker. The file MUST be an ANSI formatted file with UNIX style line endings for git to parse it correctly. This is the most likely cause of "error: Sparse checkout leaves no entry on the working directory" errors.

1. From a parent of the directory you wish to be the root folder, assuming a folder name of "src" do the following, This grabs the whole repo (which is still required), but does importantly does not perform a checkout, and correctly sets up the origin remote and branch tracking.

   git clone –n <your repository> src
   

2. You should have a fairly empty looking src folder (it will have the .git hidden folder). Now run the following. This updates the local git config to turn on sparse checkouts, and creates a file in the .git/info hidden folder that will list all the folders you want to include when doing a sparse checkout. This can be edited later to add other folders. Important: Be sure to use a git bash prompt for the below, and use an editor supporting unix line-ending conventions and save as ANSI when editing the sparse-checkout file, or you may get "error: Sparse checkout leaves no entry on the working directory" errors. The <path you want to checkout> might look like this: path/to/subfolder - note the lack of leading and trailing path separators.

   cd src
   git config core.sparsecheckout true
   echo <path you want to checkout> >> .git/info/sparse-checkout
   

3. Now you are ready to checkout. This should leave just the sparse-checkout folders populated. If it doesn’t, carefully check your spelling of everything above!

   git checkout <branch-name>
   

Edit - Echo in Powershell

I recently discovered that echo in powershell is a synomym for write-output. It's possible to get ASCII output by piping the echo to the out-file command which allows you to specify an encoding. So this will work from Powershell and give the correct file contents:

echo some/sub/folder/you/want | out-file -encoding ascii .git/info/sparse-checkout
