import VuePreview from 'vue-preview'

// defalut install
Vue.use(VuePreview)

// with parameters install
Vue.use(preview, {
mainClass: 'pswp--minimal--dark',
barsSize: {top: 0, bottom: 0},
captionEl: false,
fullscreenEl: false,
shareEl: false,
bgOpacity: 0.85,
tapToClose: true,
tapToToggleControls: false
})

上面代码中Vue.use(preview,{...}) 应改为Vue.use(VuePreview)
