在从另一台电脑Copy并完整的解压一整个Luban-lite工程后，直接执行m命令后发现编译报错
明明环境没有问题，代码也没有做任何改动，却就是编译不通过？
在sdk的命令端口执行set命令后，
set发现srctree 环境变量指向了错误的路径:
srctree=D:\Project\my_project\luban-lite在命令行中执行：
set srctree=D:\luban-lite812new\luban-lite然后重新执行 m 编译。即可
因为以前在 D:\Project\my_project\luban-lite 做过开发，可能当时某个脚本把 srctree 写入了系统环境变量。之后即使换了工程目录，这个系统环境变量一直没变。
从右键"此电脑" → 属性 → 高级系统设置 → 环境变量可以看到，将他删除掉即可，避免以后再出现这种情况
