我是 C++ 新手，并试图在 Platformio 中编译简单的 arduino 项目。

platformio.ini 文件：

    [platformio]
src_dir = .
lib_extra_dirs = .piolibdeps/, ../../

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
lib_deps = 
#    PubSubClient
    painlessMesh

main.ino 文件：

#include <Arduino.h>
#include <painlessMesh.h>
void setup()
{
}

void loop()
{
}

应该很简单，但我收到下一个错误：

“ArduinoJson6100_100::DynamicJsonDocument”没有名为“nestingLimit”的成员

完整的编译器堆栈：

在文件夹 test4 中执行任务：platformio run <
