Cannot read properties of undefined (reading 'close')

问题: Cannot read properties of undefined (reading 'close')

回答: 这个错误通常是由于尝试读取一个未定义的属性而引起的。根据引用的内容，问题可能是在代码中某个地方拼写错误或者使用了一个不存在的属性。你可以根据错误提示中的文件名和行数，迅速定位到错误的代码。在上面的错误信息中，at提示是从下往上报的，所以我们应该从最上面的at提示开始查找错误。另外，你可以取消注释掉console.log(this.option)这行代码，通过打印输出this.option来查看它的值，以帮助你进一步定位问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
