[编译]如何解决“FAILED: .../sa_profile/merged_sa_profile.zip"的错误

在执行全量编译rk3568的target时候，遇到下面的错误信息：

从上面错误中，看不出来是哪个文件造成的，考虑在python代码中添加打印语句来判断执行到哪一个文件出现错误，打印语句如下：


在merge_sa_info.py", line 106 中加上打印文件名信息
            print(merged_file)

然后直接在命令行窗口执行上面的命令：
/usr/bin/env ../../build/ohos/sa_profile/sa_profile_merge.py --src-sa-install-info-file packages/phone/sa_profile/src_sa_install_info.json ......

执行命令后，发现处理cloudfileservice.json文件的时候出现错误，直接打开这个文件，发现格式存在问题，修改这个文件，然后重新执行build命令，问题解决。

./build.sh --product-name rk3568 --ccache

总的来说，对于编译过程中出现的python代码执行的错误，可以添加调试语句来查找root cause，然后解决问题。
