用于vue-cli的Webpack dev服务器：错误产生EACCES

Question

我的环境：

Centos 7通过VirtualBox（安装在Windows 7上）
节点版本：6.10.3
NMP版本：3.10.10
我是公司代理的幕后黑手

我用vue-cli初始化了一个新项目“vuetest”，现在我想运行一个webpack服务器。我使用以下命令：

npm run dev

这个命令相当于“webpack-dev-server --open --hot”，这是我的“package.json”文件来检查：

{
  "name": "vuetest",
  "description": "A Vue.js project",
  "version": "1.0.0",
  "author": "",
  "private": true,
  "scripts": {
    "dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",
    "build": "cross-env NODE_ENV=production webpack --progress --hide-modules"
  },
  "dependencies": {
    "vue": "^2.3.3"
  },
  "devDependencies": {
    "babel-core": "^6.0.0",
    "babel-loader": "^6.0.0",
    "babel-preset-env": "^1.5.1",
    "cross-env": "^3.2.4",
    "css-loader": "^0.25.0",
    "file-loader": "^0.9.0",
    "vue-loader": "^12.1.0",
    "vue-template-compiler": "^2.3.3",
    "webpack": "^2.6.1",
    "webpack-dev-server": "^2.4.5"
  }
}

但是我收到以下错误：

> vuetest@1.0.0 dev /var/www/html/vuetest
> cross-env NODE_ENV=development webpack-dev-server --open --hot
