当你在使用Python时，如果遇到 ModuleNotFoundError: No module named 'formatter' 的错误，这通常表示你的代码中引用了一个名为 'formatter' 的模块，但是Python解释器无法找到这个模块。

这个问题发生在Ubuntu22.04上安装python2.7后，通过repo同步源代码的时候出现的。

分析：formatter已在python3.4+标记成废弃接口，就算你按照网上教程添加这个模块也无法解决。

经过查询资料，https://gerrit-review.googlesource.com/c/git-repo/+/303282
有提供的解决方法：

实际操作如下：

查看repo报错信息，找到help.py的具体路径，例如： .repo/repo/subcmds/help.py

然后给help.py打上图的补丁即可解决问题。

打补丁后的文件如下：
