I can´t install nodemon globally, “nodemon” not recognized

Question

i wanna use nodemon for monitoring my node.js app's, then i execute the next line command:

npm install -g nodemon 

or

npm install nodemon -g

When I move to my app folder and try to to

nodemon app.js

The system tells to the next:

"nodemon 'is not recognized as an internal or external command, program or batch file.

Answer 1

Since node prefix is not in the PATH ENV variable , any of the globally installed modules are not getting recognized.

Please try this.

Open cmd prompt

npm config get prefix

append the resulting path to PATH env variable.

Now you should be able to run nodemon from any location.

This is what i have done on my local machine

C:\>npm config get prefix
C:\Users\username\AppData\Roaming\npm

C:\>set PATH=%PATH%;C:\Users\username\AppData\Roaming\npm;

C:\>nodemon

I also got same error as you with this command:

$ sudo npm install -g nodemon

I just really switched as "root" and then just ran:

$  npm install -g nodemon

I think npm has a bug to not work with sudo, but it works fine when you are really "root".

Answer 3

You can add path to node packages in System Path variable. Add "C:\Users\UserName\AppData\Roaming\npm".

Linux users: I would highly suggest not using sudo or root user to install npm packages. This could become a security problem especially on a production system. I would also suggest not trying to hack permissions as I have hosed an Ubuntu system by not reading the warning on the npmjs procedure.

It would be better to configure npm to use a folder owned by the current user. Simplest approach

wget https://raw.githubusercontent.com/pcnate/npm-configure/master/add-npm-global.sh -q -O - | bash
npm install -g nodemon

Or get the code script on github to see how it works

See details on the npmjs website

Answer 10

This command worked for me.

If your global installation didn't work then install it in your development dependency.

npm install --save-dev nodemon

Answer 11

had the same problem otherwise was just working fine a day ago. Very simple fix first check if nodemon exists on your system globally or not

To check

npm list -g --depth=0

If you don't see then install it npm install -g nodemon (g stands for globally)
If you see it still doesn't work then you need to configure environment variable I use Windows OS. On Windows navigate to

Control panel>System>Advanced System Settings>Environment Variables>double-click on PATH

Now check if you have this PATH C:\Users\yourUsername\AppData\Roaming\npm
If not, you will see some existing paths, just append to it separating with semicolon. That's it! Worked for me. For me node was installed in C:..\Roaming\npm and for you if the PATH is different, you will put in whatever applcable.
