npm中找不到nodemon怎么解决运行服务器时发生

Question

我有一个问题：nodemon 没有运行 npm 脚本（例如 npm 启动），但是如果在 npm 脚本之外的命令行上调用 nodemon，nodemon 运行正常。

$ nodemon server.js
11 Feb 22:59:51 - [nodemon] v1.3.7
11 Feb 22:59:51 - [nodemon] to restart at any time, enter `rs`
11 Feb 22:59:51 - [nodemon] watching: *.*
11 Feb 22:59:51 - [nodemon] starting `node server.js`

在 npm 脚本中如何调用它：

package.json

{
...
  "scripts": {
    "start": "nodemon server.js"
  }
}

运行 npm 启动脚本时：

$ npm start
> aaa@0.0.1 start /home/akul/Documents/aaa
> nodemon server.js

sh: 1: nodemon: not found

您可以通过在系统中全局安装 nodemon 来解决此问题。

npm install -g nodemon --save-dev

当 /node_modules/.bin 中不存在 nodemon 时，就会出现问题。

添加了 --save-dev ，因为它仅在开发过程中需要。
