为什么我不能在OSX 10.8.4上安装nodemon或supervisor？

Question

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.我尝试以管理员身份运行sudo npm install supervisor -g似乎有效,但是当我删除/添加一些js代码时没有.有任何想法吗？

PS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.

晚了,但重要的是要注意你应该避免sudo在安装npm时使用.sudo npm install当您向计算机提供任意脚本root访问权限时,这是一个巨大的安全风险.

相反,你应该让自己成为NPM目录的所有者

sudo chown -R $USER /usr/local

然后

sudo chown -R $USER ~/.npm

现在你应该能够在没有sudo的情况下运行命令:

npm install supervisor -g --save

Answer 2

您遇到EACCES错误,这意味着您无权/usr/local/lib/node_modules/nodemon在Mac OS X中以标准用户身份创建目录.

有两种解决方案:

• 使用与超级用户运行相同的命令sudo.该软件包将安装在/usr/local/lib/node_modules.
• 更改npm的设置,将所有全局包安装到您的用户拥有的私人文件夹之一.请参阅此相关答案,逐步说明该过程.
