【问题描述】：
我正在学习 Vue.JS。我安装了 cli 并创建了一个项目：
$ npm install -g vue-cli
$ vue init webpack-simple vue-example
$ cd vue-example
$ npm install
$ npm run dev # this is where problem starts!
我收到此错误消息：
> vue-example@1.0.0 dev /Users/me/Code/vue/vue-example
> cross-env NODE_ENV=development webpack-dev-server --open --hot
Project is running at http://localhost:8080/
webpack output is served from /dist/
404s will fallback to /index.html
loaderUtils.parseQuery() received a non-string value which can be problematic, see https://github.com/webpack/loader-utils/issues/56
parseQuery() will be replaced with getOptions() in the next major version of loader-utils.

我在 vue-cli 版本 2.8.1（最新）和早期版本（2.5.0）上都试过了，但没有成功。
有人知道如何解决这个问题吗？似乎默认值应该开箱即用......
我是 Vue / webpack 的新手，所以请放轻松。
【问题讨论】：
-
看起来像是 CSS 语法问题。
-
我找到了 github repo 并按照说明操作，它对我有用。你已经安装了 npm 还是新安装的？您在运行 npm install 时是否看到任何错误？我有时不得不运行 npm install 两次才能修复错误。你可以试试。
-
我也有同样的问题。我使用的是 Windows 10。尽管有消息，但这不是 CSS 问题。即使你只是在你的 .vue 中放了一个空白的 标签，它也会发生。我的预感是我的全局 npm 包中的某些东西是罪魁祸首。我要找一个虚拟机做一个测试。
-
AWS Linux 上的同样问题。
-
是的，我需要获取最新版本的节点和 npm。谢谢大家！
