已尝试无效方案 #

• 更换多个版本的Google Ad SDK
• 更换不同Unity版本

排查解决步骤 #

• 检查系统环境变量：确认系统Path变量中包含C:\Windows\System32（cmd.exe所在目录），若缺失则添加，添加后重启电脑生效。
• 配置Unity终端路径：打开Unity编辑器，依次进入Edit > Preferences > External Tools，将Terminal设置为系统默认cmd，或手动指定路径C:\Windows\System32\cmd.exe。
• 以管理员身份运行Unity：避免权限不足导致无法调用系统命令工具。
• 清理项目缓存：删除项目目录下的Library、Temp、.utmp文件夹，重新构建项目。
• 修正NDK/SDK路径：将Unity使用的NDK/SDK移动到无空格、无特殊字符的路径下（例如原路径D:\Unity Assets\Sdk可改为D:\UnitySDK），并在Unity的External Tools中更新对应路径。
