有位网友编译了鸿蒙OpenHarmony 2.0（HarmonyOS 2.0）的源码，按照其给出的具体步骤都无法顺利的编译通过，并且在编译过程中产生了以下错误问题，经过摸索，已解决了该问题，编译鸿蒙OpenHarmony 2.0源码顺利完成，以下分享方法。

解决方法 以上问题大致上解决了。 解决办法是编译，先把官方鸿蒙全量代码下载到本地，从Gitee下对应的vendor替换就可以编译通过了。（目测全量下载有一定的差异。）
参考：华为鸿蒙HarmonyOS开放源代码OpenHarmony的地址公布，附获取方法。
相关事项说明 1、关于升级scons的尝试 测试过几个版本了：scons-3.0.4、scons-3.1.2、scons-4.0.1，还是一样的报错内容。 2、所使用的python版本太高 官方教程搭建环境要求python3.7以上，我尝试过用python2.7搭建，但有很多模块装不上。
