拉取Unreal Engine 5分支后本地Git仓库被锁定的解决问询

我首次拉取EpicGames的Unreal Engine 5仓库（开发分支ue5-main），并创建了本地分支katianie-ue5-main。但在Visual Studio中构建项目时，所有文件都提示访问被拒绝，Windows资源管理器显示所有文件均为只读状态。手动取消文件夹的只读属性后没有效果，请问有没有解锁文件夹的方法？Git Desktop有没有相关的checkout操作可以解决这个问题？

1. 重置Git文件权限 #

进入仓库根目录，打开Git Bash或命令提示符，执行：

git config core.filemode false
git reset --hard HEAD

这条命令会修正Git管理的文件权限，并将本地文件重置为当前分支的最新状态，解决因Git权限标记导致的只读问题。

2. 强制清除Windows只读属性 #

• 右键仓库文件夹→属性，取消只读勾选，点击应用，选择将更改应用于此文件夹、子文件夹和文件后确定。
• 若上述操作无效，以管理员身份打开命令提示符，执行：

attrib -r -s /d /s "你的UE5仓库完整路径\*"

该命令会递归移除整个仓库的只读和系统属性。

3. Git Desktop操作步骤 #

• 点击仓库分支下拉菜单，选择ue5-main分支并点击Checkout，回到干净的远程分支状态。
• 重新创建本地分支katianie-ue5-main（确保基于未修改的ue5-main）。
• 或者直接在Repository菜单中选择Discard All Changes，一键重置本地文件状态。

4. 构建前置检查 #

• 必须以管理员身份运行Visual Studio，避免系统权限限制。
• 确保仓库路径无中文、空格或特殊字符，建议使用纯英文路径。
