ERROR in
Vue packages version mismatch:
This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.
@ ./main.js 15:11-27
卧槽，简直了，只要我import app.vue 就报错，无论我app.vue有木有写东西，都报错，我也是醉了
回来发现，原来是我的package.json里面忘记依赖了vue-loader,好吧，我赶紧依赖了一下，结果又报错，说我vue-loader和vue-template-complier版本不一致
我赶紧把版本改成一致的，然后，npm install，结果还是这么报错。
最后上了大招，直接在node-modules文件夹下面把不一致的vue-loader和vue-template-complier文件夹干掉之后，再重新npm install 终于ok了！！！
