Mac OSX El Capitan 10.11.6和Wemos D1上传草图时报错怎么解决？

你好！
我在装有 Mac OSX El Capitan 10.11.6 和 Wemos D1 迷你板的 Macbook 中运行 Arduino IDE 1.6.8，在尝试上传基本草图时出现以下错误：
代码：全选Sketch uses 219,439 bytes (21%) of program storage space. Maximum is 1,044,464 bytes.
Global variables use 31,140 bytes (38%) of dynamic memory, leaving 50,780 bytes for local variables. Maximum is 81,920 bytes.

这是我的工具配置的样子：
当我点击上传时，我看到板上的串口 LED 灯闪烁了几秒钟，然后出现了这个错误。
我是这个板的新手，我需要连接什么东西吗？我没有连接到 D1 迷你板，我有 2 个新板并尝试使用它们，但我遇到了同样的问题，我也尝试过使用不同的 USB 电缆。
请帮忙！谢谢！
