问题
使用make otapackage 编译失败, log 如下:

分析
请同事尝试编译, 他那边的代码是正常的, 无法确认根源.
在上面的LOG中 : os.path.join(os.environ[“OUT”],“system.img”)
没写过PY脚本, 假设性地查看了下 OUT 环境变量发现,
我的环境下, OUT是空的. 而同事的OUT目录指向的却是源码编译的OUT目录.
于是找了另外一台PC验证了下, 尝试给OUT赋上正确的值, 结果编译通过了, 那么问题根源找到了.
而后, 对比编译命令发现, 我缺少了执行lunch xxx命令.
惯性所致, 习惯了旧的SDK上, source 完 envsetup.sh 后, 自动lunch了
PS: 有个小插曲, 刚开始并不会报这个错误, 因为我先编译了5.1的代码, 而其中, OUT变量已经赋了值, 虽然不正确, 但不会导致编译失败
