vue2遇到的一些错误

一、VUE中的VUEX如何调用modules里面的mutations和state

 

...mapMutations("workflow",['setApproverConfig', 'setApprover']),

二、Non-nested routes must include a leading slash character. Fix the following routes: - JSExpression

 

出错点

Non-nested routes must include a leading slash character. Fix the following routes:

非嵌套路由必须包含前导斜杠字符

{ path: '/JSExpressionTest', name: 'JSExpressionTest', component: () => import('@/components/JSExpressionTest') }

三、Vue报错：contains both .browserslistrc and package.json with browsers

删除.browserslistrc文件就好了

四、ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

运行别人的vue项目时，先使用npm install命令，再使用npm run serve命令。

在使用npm run serve命令时报错，错误如下：

ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

options has an unknown property ‘disableHostCheck’. These properties are valid: object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?, host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetup Middleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocketServer? }

解决方法如下：

注释这一行即可
