mac vscode的esp-idf案例helloworld环境部署问题

Question

macos 13.2.1
vscode Version: 1.79.2 (Universal)
esp-idf v5.1.0

你好，我是mac电脑安装了vscode和esp-idf。为什么显示identifier "CONFIG_IDF_TARGET" is undefined和identifier "CONFIG_FREERTOS_HZ" is undefined，是不是哪里没有配置好。

先检查两个缺失文件的宏定义，看看esp-idf开发环境有没有配置好，用命令检查下：

idf.py --version
