在Vue项目中遇到“the computed property "config" is already defined in data”的错误,通常意味着在组件的data和computed属性中同时定义了名为config的属性。为了解决这个问题,我们需要检查并修改代码以避免重复定义。以下是解决这个问题的步骤: 确认报错信息: 确认Vue项目中确实存在“the computed property 'config' ...
「Vue warn」:The computed property "data" is already defined in data 这是因为你 data 里面定义了又在 computed 里面定义这个属性,如果没有请检测你是否使用了混合,可能在混合里面定义的,计算属性的名字不能与 data 中属性同名,
enableAutoClasses: false, classNames: { touched: 'touched', // the control has been blurred untouched: 'untouched', // the control hasn't been blurred valid: 'valid', // model is valid invalid: 'invalid', // model is invalid pristine: 'pristine', // control has not been interacted ...

VUE 解决:Method "xxx" has already been defined as a data property. 代码写法: 2.解决方法:改变方法名。我其实不太理解,为什么不能用那个名字。依旧只能猜测可能类似java的保留关键字吧。
'Data field "' + key + '" is already defined ' + 'as a prop. To provide default value for a prop, use the "default" ' + 'prop option; if you want to pass prop values to an instantiation ' + 'call, use the "propsData" option.', ...

$options.props) { warn(`The computed property "${key}" is already defined as a prop.`, vm) } } } } 3. 为每个计算属性做响应式处理 const sharedPropertyDefinition = { enumerable: true, configurable: true, get: noop, set: noop } export function defineComputed ( target: any, key: ...
