專案重新部署時，遇到的一個錯誤

即：
These dependencies were not found:

* !!vue-style-loader!css-loader?{"sourceMap":false}!../../._vue-loader@13.7.0@vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-3483e884","scoped":true,"hasInlineConfig":false}!./style/crop.css in ./node_modules/._vue-core-image-upload@2.4.1@vue-core-image-upload/dist/crop.vue

To install them, you can run: npm install --save !!vue-style-loader!css-loader?{"sourceMap":false}!../../._vue-loader@13.7.0@vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-3483e884","scoped":true,"hasInlineConfig":false}!./style/crop.css !!vue-style-loader!css-loader?{"sourceMap":false}!../../._vue-loader@13.7.0@vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-80f84954","scoped":false,"hasInlineConfig":false}!./style/style

查找了很久，原因是以前vue-core-image-upload是2.3.10版本，最新的官方地址vue-core-image-upload版本是2.4.1會有問題。2.4.1版本就會出現上面問題。將版本固定到2.3.10即可
執行如下命令：

cnpm i --save vue-core-image-upload@2.3.10
