Uncaught SyntaxError: Unexpected identifier 報錯 import Vue from 'vue';

通常狀況是由於Webpack與webpack-dev-server版本不兼容致使。

package.json

能夠直接粘貼進去，若是還有錯 npm install下

再npm run dev

像我也出現此問題，我電腦的webpack是1.13.1，但webpack-dev-server是2.x以上的版本。
當我將webpack-dev-server卸載掉：npm uninstall webpack-dev-server -g
而後安裝1.15.0版本的webpack-dev-server，就可解決了此問題。：npm install webpack-dev-server@1.15.0 -g
