楼主在做尚学堂英文单词打卡的案例吧？我也遇到这个问题，这是鸿蒙API升级到12 有更严格的语法约束，声明变量要给默人值：
可以给空

可以初始化

option:string = "";<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

或者?: 可不存在

option?:string<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

或者追加类型，并初始化

option:string|undefind = undefind<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>
