Uncaught runtime errors: × ERROR Cannot read properties of null (reading 'isCE')是一个常见的错误,通常出现在Vue项目中。这个错误的原因是尝试读取一个空对象的属性。根据您提供的引用,这个错误可能与Vue项目中使用的vue-router库有关。可能的解决方案是卸载当前版本的vue-router,并安装与Vue2兼容的版本,如引用所示。<span class="em">1</span><span class="em">2</span>

Uncaught runtime errors: × ERROR Cannot read properties of undefined (reading 'config')
出现这个错误通常是因为在代码中尝试读取一个未定义的属性。可能有几个原因导致这个问题:
1. 变量未声明或未初始化:请确保你的代码中声明并初始化了相应的变量。
2. 对象不存在或为空:在访问对象的属性之前,请确保该对象存在并已正确赋值。
3. 异步操作未完成:如果代码涉及异步操作,例如从服务器获取数据,确保在访问属性之前等待异步操作完成。
如果你能提供更多代码或错误堆栈跟踪,我可以给出更具体的建议来解决问题。
Uncaught TypeError: Cannot read properties of null (reading 'isCE')
This error occurs when you are trying to access a property or method of an object that is null or undefined.
For example, if you have the following code:
```
let myObject = null;
console.log(myObject.isCE);
```
You will get the "Uncaught TypeError: Cannot read properties of null (reading 'isCE')" error because myObject is null and does not have an isCE property.
To fix this error, you should check if the object is null or undefined before accessing its properties or methods.
Here's an example of how you can fix the above code:
```
let myObject = null;
if (myObject !== null && myObject !== undefined) {
console.log(myObject.isCE);
}
```
This code checks if myObject is not null and not undefined before trying to access its isCE property.
