如何修复 ESP32 错误: 'portTICK_PERIOD_MS' was not declared in this scope

问题：

尝试编译 ESP-IDF 固件（带或不带 PlatformIO）时，你看到类似这样的错误消息

espidf_porttick_error.txt

src/main.cpp:13:27: error: 'portTICK_PERIOD_MS' was not declared in this scope
    13 |         vTaskDelay(1000 / portTICK_PERIOD_MS);

src/main.cpp:13:27: error: 'portTICK_PERIOD_MS' was not declared in this scope
    13 |         vTaskDelay(1000 / portTICK_PERIOD_MS);

通过在发生错误的文件顶部（此示例中为 src/main.cpp）添加以下行来包含 FreeRTOS：

freertos_includes.cpp

#include <freertos/FreeRTOS.h>
#include <freertos/task.h>

#include <freertos/FreeRTOS.h>
#include <freertos/task.h>
