通过文档资料百度网盘下载配套资料，学习手册目录中有嵌入式Linux应用开发完全手册V5.1_STM32MP157_Pro开发板.pdf，里面有详细的开发环境搭建步骤，但是在搭建过程中还是遇到了一些问题，记录如下：
ModuleNotFoundError: No module named ‘requests’
../repo/repo init -u https://gitee.com/weidongshan/manifests.git -b linux-sdk -m stm32mp1/100ask_stm32mp157_pro_release-v2.0.xml --no-repo-verify

import requests
ModuleNotFoundError: No module named 'requests'解决方法：
python -m pip install requestsModuleNotFoundError: No module named ‘formatter’
formatter已经在python3.4标记成废弃接口，在python3.10已经正式删除，并且其依赖的cStringIO也已经删除。所以不能简单的安装formatter模块，可以通过两种方式解决：
方法一：降低python版本到3.9以下
- 添加 ppa 源，此源可安装多个 python 版本
sudo add-apt-repository ppa:deadsnakes/ppa- 安装 python3.9
sudo apt install python3.9- 建立 python 的组,并添加 Python3.9 的可选项，优先级为 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.9 1- 验证当前 python 是否是 3.9 版本
python --version- 如果不是，用以下命令手动配置一下
sudo update-alternatives --config python方法二：修改repo源码
将repo/repo/subcmds/help.py文件替换为如下内容：
也可以参考Google修复后的代码，根据diff修改文件。
