Do you have express module installed?

Ok then. So, if you run node in the directory where you're running your test, you can do a var express = require('express'), I assume. Do you have any other instance of node.js running on your machine?

[js08]

can you share a screenshot..how to do it...i am confused with what your saying....

[rodrigo-medeiros]

i am confused with what your saying....

No problem. You said that you have express installed. But is it installed globally or only in one directory? Like, based on what you explained, you installed expressworks in C:\Users\Desktop\node-school\express. If you have express installed globally or at least in this folder, when you run npm ls express inside this folder, it'll show which version is installed. If it's not installed, it'll show (empty). In this case, just run npm install express from the same directory. If the existence of express is not the problem, you need to check if there isn't another instance of node running with the command (you're on a Windows box) taskkill /F /im node.exe. If none of the two solutions work, post here.

@rodrigo-medeiros yeah it shows empty do i need to run this command in terminal taskkill /F /im node.exe

[rodrigo-medeiros]

If it's not installed, it'll show (empty). In this case, just run npm install express from the same directory.

express is not a dependency of expressworks, but in order to run a node.js file that require('express'), you have to install it manually with npm install express. Just do it and you'll be good to go.

@rodrigo-medeiros yeah its working...can u tell me how this command will work taskkill /F /im node.exe just curious to know

[rodrigo-medeiros]

Sure. taskkill is the Windows equivalent to Unix kill. In other words: it'll kill processes (or tasks, in Windows). The /F is to force the process to exit, because if the OS sees that this process is doing something, it might want to wait it finish the job. And the /im is the option that you use to pass the name of the process you want to kill (in your case, node.exe).

@rodrigo-medeiros i use git shell can i execute this commands in git shell

[rodrigo-medeiros]

Yes, you can: they're Windows commands.

[js08]

@rodrigo-medeiros can you give those commands I wanted to try it out

[rodrigo-medeiros]

Sorry @rk08, I don't undersand what you mean. Which commands?

[js08]

I WANTED GIT SHELL COMMANDS FOR THIS taskkill

[rodrigo-medeiros]

Well @rk08, on Windows you can use taskkill on cmd or git bash. But I'm not sure if the Unix kill command will work on git bash. You can it try yourself: follow this link that shows briefly how to use it.
