Unity构建游戏时反复抛出CS0246错误求助

报错信息： #

Library\PackageCache\com.unity.ugui@1.0.0\Runtime\EventSystem\EventData\PointerEventData.cs(235,16): error CS0246: The type or namespace name 'PenStatus' could not be found (are you missing a using directive or an assembly reference?)

解决步骤： #

• 检查Unity版本与UGUI包兼容性：PenStatus是Unity 2022.x及以上版本引入的类型，若使用旧版本引擎，UGUI包版本可能不匹配。打开Package Manager，找到com.unity.ugui，切换到与当前引擎匹配的版本。
• 重建UGUI缓存：删除项目目录下的Library/PackageCache/com.unity.ugui@1.0.0文件夹，重启Unity，让引擎自动重新下载并导入正确的UGUI包文件。
• 验证平台输入模块：打开Unity Hub，找到当前使用的Unity版本，点击右侧三个点→添加模块，检查是否勾选了对应平台的笔/触控支持模块（比如Windows平台的「Windows Pen and Touch Support」），该类型依赖这些模块。
• 重置项目设置：在编辑器中依次点击Edit → Project Settings → Editor，找到「Reset All Settings」选项，重置后重新尝试构建。
