我正在尝试编译我的第一个 ESP32 示例项目。我使用所有最新工具设置 Visual Studio Code。（Python、工具链等）。我不确定我到底需要什么，因为我是这个环境的新手，所以也许我错过了一些东西。
我遵循了关于如何创建和编译第一个项目的用户指南，我使用了示例文件夹中的 Blink 项目。
这是我得到的。

我从 blink.c 中删除了所有内容以避免代码错误。
眨眼.c
#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/gpio.h"
#include "sdkconfig.h"
/* Can use project configuration menu (idf.py menuconfig) to choose the GPIO to blink,
or you can edit the following line and set a number here.
*/
#define BLINK_GPIO 0x01
void app_main(void)
{
while(1) { }
}
另一个问题，有一个运行选项 idf.py menuconfig。有时它有效，有时它说：
C:\ESP32_projects\blink>idf.py menuconfig
'idf.py' is not recognized as an internal or external command,
operable program or batch file.
任何帮助将不胜感激！
