并且按照官方文档的提建议我把get_idf作为一个激活指令，而不是把export.sh加入环境变量。
于是乎，我想着在vs c插件里配置使用已经搭建好的idf,然而进入 Advance 选择存在的idf（/opt/esp/esp-idf-v4.4/）、idf/tool（/opt/esp/esp-idf-v4.4/tools/）、py虚拟环境（/home/kearney/.espressif/python_env/idf4.4_py3.10_env/bin/python）之后Install，vsc提示command fail,内容如下

这里不建议您直接将 export.sh 添加到 shell 的配置文件。因为这会导致在每个终端会话中都激活 IDF 虚拟环境（包括无需使用 IDF 的情况），从而破坏使用虚拟环境的目的，并可能影响其他软件的使用。”。那么我是否可以从idf插件配置中加入这些参数呢？

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:
