运行安卓版本工具的ota_from_target_files时，"OSError：[Errno 2]没有这样的文件或目录“

Question

当我使用Android版本工具运行ota_from_target_files时，我尝试了很多种格式，但都没能找出我OSError: [Errno 2] No such file or directory错误的来源。

parallels@ubuntu:~/Git$ /home/parallels/Git/build/tools/releasetools/ota_from_target_files /home/parallels/Git/tmp/ota-dest.zip /home/parallels/Git/tmp/ota_update.zip

检查imgdiff工具是否可用：find out/host/ -name "*imgdiff*"

尝试运行make otatools来构建imgdiff可执行文件。
