node.js – 为什么我不能在OSX 10.8.4上安装nodemon或supervisor？

我只是尝试使用终端安装nodemon或supervisor,我不断收到这个我不明白的错误.我尝试以管理员的身份运行sudo npm install supervisor -g似乎工作,但是当我删除/添加一些js代码时没有.有任何想法吗？

附：我在预先存在的模板上运行它,我的依赖项是

"dependencies": {
    "mongoose": "~3.6.15","express": "~3.3.4","jade": "~0.34.1","email-validator": "~0.1.2"
  }

当我尝试sudo时,这就是发生的事情：

sudo npm install supervisor -g --save 
password:
npm http GET https://registry.npmjs.org/supervisor
npm http 304 https://registry.npmjs.org/supervisor
/usr/local/bin/node-supervisor -> /usr/local/lib/node_modules/supervisor/lib/cli-wrapper.js
/usr/local/bin/supervisor -> /usr/local/lib/node_modules/supervisor/lib/cli-wrapper.js
supervisor@0.5.6 /usr/local/lib/node_modules/supervisor

这似乎有效.但是在应用程序代码中我开始添加和删除javascript并单击“保存”,但除非我在终端内重新启动服务器,否则不会发生效果.
