解决 Arduino IDE 无法安装 ESP32 开发板的问题
尽管 Arduino IDE 可以设置代理，但是有些时候即使设置了代理也无法下载，这时就需要手动安装了。
这份快速笔记是针对 macOS 系统准备的，如果你使用的是 Windows 或 Linux，可能并不能完全解决你的问题。
首先打开官方仓库 arduino-esp32，选择你需要的版本号（ Git Tag ），然后点击右边绿色 Code 选择 Download ZIP。
提示
不要从 Arduino IDE 板管理器的地址下载，你如果从这个地址下载则需要手动安装全部依赖（ 截止 3.1.3 版本需要下载 10 个 ）
下载完成后拷贝到路径 /Users/user/Library/Arduino15/packages/esp32/hardware/esp32/3.1.3（ 注意根据实际情况修改用户名和版本号，后面不再赘述 ）
然后终端进入 /Users/user/Library/Arduino15/packages/esp32/hardware/esp32/3.1.3/tools 运行 python3 get.py，此时会自动安装所需的全部依赖：

Platform Tools Installed # 当你看到这个时，依赖就全部安装完毕了这个时候再打开 Arduino IDE 选择一个 ESP32 开发板，打开一个 Blink 例程，点击 verify 看看编译是否存在问题，按理说是不会有问题的，祝你好运 😃
