Vue报错:Uncaught TypeError: Cannot assign to read only property’exports‘ of object’#Object‘的解决方法
该错误出现在控制台报错信息中: "Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '$treeNodeId')"。错误提示表明在某个地方尝试读取了一个未定义的属性"$treeNodeId",导致出现了错误。
常见的出现这种错误的原因是访问了一个不存在或未定义的属性。根据引用中的分析,当你访问一个对象的属性时,如果该对象是空对象或未定义,就会出现这个错误。
为了解决这个错误,你可以先检查在访问属性之前确保对象已经被正确地初始化或赋值。在你的情况下,如果你要访问"$treeNodeId"属性,你需要先确保该属性所属的对象已经被正确地定义和赋值。
你可以检查代码中的相关部分,确认是否正确地定义并初始化了对象,或者在访问属性之前进行一些判断,以避免访问未定义的属性。确保在使用属性之前,所有相关的对象都已经被正确地初始化和赋值,以避免出现这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
