vue3无法使用vue-devtools

const app = createApp(App) .use(router) .use(i18n) .use(lazyPlugin,{ loading:require('@/assets/images/default.png'), // 图片加载时默认图片 error:require('@/assets/images/error.png')// 图片加载失败时默认图片 }) .mount('#app') //add support for vue-devtools const win = window; if(process.env.NODE_ENV === 'development'){ if('__VUE_DEVTOOLS_GLOBAL_HOOK__'inwin){ win.__VUE_DEVTOOLS_GLOBAL_HOOK__ = app; } }
