【问题讨论】：
【参考方案1】：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。我猜在 FireBase 库之前更新了板软件。我在this page 上找到了这个解决方案。
【讨论】：
关于您使用的链接，最好链接到存储库中的实际问题，而不是参与摘要，其中可能不包含有关此问题的信息在未来的某个时间点（即当该用户的其他更新的参与将其从该列表中推出时）。【参考方案2】：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！ 这就是弹出错误消息的原因。
【讨论】：
【参考方案3】：使用 platformio，更改 platformio.ini（为我工作），用于最新的 2.x 版本：
平台 = espressif8266@^2
