Vue报错:Uncaught TypeError: Cannot assign to read only property’exports‘ of object’#Object‘的解决方法
这个错误是由于在读取一个null对象的属性时引发的。具体地说,错误信息中提到了'getBoundingClientRect'属性。根据引用的描述,这个错误可能是由于在canvas元素上调用'getContext'方法之前,未能正确获取到相应的dom元素。在开发中,我们应该首先确保dom元素已经成功获取到,然后再进行相关操作。另外,根据引用的说法,我们还应该在使用某个对象的属性或方法之前,先进行判空操作,以避免引发类似的错误。因此,在处理这个错误的时候,你可以检查一下是否正确获取到了canvas元素,并在调用相关方法之前进行判空操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
