请在 esp-idf 目录运行 git submodule update --init，并执行 ./install.sh，确保正确安装了 IDF Component Manager: https://docs.espressif.com/projects/esp ... nager.html
如果还报告该错误，请在 main 目录下的idf_component.yml 文件内，删除 version 信息，取消其版本检测。

感谢您的解答回复！！问题已解决，是我的环境搭建有问题

解决办法：删除电脑中所有与IDF有关的环境变量。

PS：该方法虽然可以正常编译下载，但还是提示缺少"modbus_params.h"文件
