npm run new -- "我的第一篇文章"

对应的配置文件是这个：

{
  "name": "hexo-site",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "build": "hexo generate",
    "clean": "hexo clean",
    "deploy": "hexo deploy",
    "server": "hexo server",
    "new": "hexo new"
  },
  "hexo": {
    "version": "7.3.0"
  },
  "dependencies": {
    "hexo": "^7.3.0",
    "hexo-generator-archive": "^2.0.0",
    "hexo-generator-category": "^2.0.0",
    "hexo-generator-feed": "^3.0.0",
    "hexo-generator-index": "^4.0.0",
    "hexo-generator-tag": "^2.0.0",
    "hexo-renderer-ejs": "^2.0.0",
    "hexo-renderer-marked": "^6.3.0",
    "hexo-renderer-stylus": "^3.0.1",
    "hexo-server": "^3.0.0",
    "hexo-theme-landscape": "^1.0.0"
  }
}

这样一来，无论在哪里，只要 git clone 下来仓库，然后 npm install 之后，就可以直接写博客了，而不用全局安装 hexo。
