git - git 克隆后损坏的 Unity 项目

Question

我有一个 Unity 项目 ( github link )，它在克隆后不起作用。即使文件在那里，它们的内容也不正确。例如 .png 文件替换为文本:

version https://git-lfs.github.com/spec/v1oid sha256:089f8198df161233681006c4243f6d6babb2e125062a21ea727d0d6c97889d26size 1035

我从外部 Assets 包(例如 DOTween)获得的一些 DLL 也可能没有正确存储，因为编译器提示未声明的命名空间。

Assets/External Dependencies/Demigiant/DOTween/Examples/Basics.cs(3,7): error CS0246: The type or namespace name `DG' could not be found. Are you missing an assembly reference?

更新:实际上，dll 甚至不存在。为什么？它们不是 gitignore 的一部分。

我已确保将 Version Control Mode 设置为 Visible Meta Files 并且 Assets 序列化模式到强制文本。

我尝试将项目移动到新目录，删除 .git 文件夹，删除 Library，重新制作所有内容(使用 Unity 重新打开，然后 git init)，然后推到一个新的 repo 协议(protocol)。新的 repo 协议(protocol)与之前的 repo 协议(protocol)存在完全相同的问题。

我正在使用 default .gitignore for Unity

以及以下 .gitattributes(启用 LFS):

更新:

经过进一步调查，似乎 png 文件在克隆后打开项目时被覆盖(被统一？)。它们正确存在于远程存储库中。另一方面，外部 dll 根本不会上传。

Answer 1

你的 .gitattributes 文件是错误的。

*.png filter=lfs diff=lfs merge=lfs -text

文本？文本？究竟为什么要将 .png 文件视为文本？大多数其他属性也是如此。

查看我的自己的 .gitattributes 文件，我有这个:
(没错，大部分都是注释行)

此文件是在我通过 GitHub 桌面应用程序创建 git 存储库时自动为我创建的。我听说它“不是很好”，但我发现它可以满足我的需要。即不要妨碍提交和推送到 GitHub。
