I am doing node.js server setup from <https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens>. I am new in node.js. I am installing `npm install nodemon --save`. But when I am run the server with this `nodemon server.js`. 

In the terminal showing: 

>

`node server.js` command is working and started the server, But `nodemon` command is not working.

I am set up the node js server from <https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens> video.

I don't know why it is not working I have tried some command for the install nodemon.

```
npm install -g nodemon 
npm install -g nodemon --save 
npm install --save-dev nodemon 
npm install -g nodemon@debug 

npm install -g --force nodemon

```

I have seen one link [I can´t install nodemon globally, "nodemon" not recognized](https://stackoverflow.com/questions/17975999/i-can%C2%B4t-install-nodemon-globally-nodemon-not-recognized), But I don't know how to set the path because of my project location in D drive. 

I want to run `nodemon server.js`. If anybody has an idea please share. Thanks in advance.
