为什么我在连接 Firebase 时会在 Arduino 中遇到这个问题？
Why am I facing this Problem in Arduino when connecting Firebase?

Error compiling for board NodeMCU 1.0 (ESP-12E Module).
This report would have more information with

当我遇到同样的问题时，我在 board manager 上回滚到 2.7.4，这导致它编译没有问题。我想板软件在 FireBase 库更新之前更新了。我在 this page.
上找到了这个解决方案
我在将代码从旧笔记本电脑转移到新笔记本电脑时发现了错误。
你猜怎么着？我最近在我的新笔记本电脑中下载的 Arduino 库版本与旧笔记本电脑中的版本不匹配！
这就是错误消息弹出的原因。
使用 platformio，更改 platformio.ini（为我工作），最新 2.x 版本：
platform = espressif8266@^2
回滚到 2.7.X 版本enter image description here
