nodemon not found in npm

Question

I have a problem: nodemon does not run off the npm script (e.g. npm start),
but if nodemon is called on the command line outside the npm script, nodemon run

Answer 1

I had this problem and even after I have used the command npm install nodemon --save in my application, I still had problem with nodemon.

I just resolved after I installed nodemon globally, using the command:npm install nodemon -g

Answer 2

for linux try

sudo npm install -g nodemon

for windows open powershell or cmd as administration

npm install -g nodemon

Answer 3

I tried to list global packages using npm list -g --depth=0, but couldn't find nodemon.
Hence, tried installing it using global flag.
sudo npm install nodemon -g
This worked fine for me.

Answer 4

under your current project directory, run

npm install nodemon --save //save in package.json so that the following code cam find your nodemon

then under "scripts" in your package.json file, add "start": "nodemon app.js" (or whatever your entry point is)
so it looks like this:

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon app.js"
}

and then run

npm start

That avoids complicate PATH settings and it works on my mac
hope can help you ;)

Answer 5

Here's how I fixed it :

When I installed nodemon using : npm install nodemon -g --save , my path for the global npm packages was not present in the PATH variable .

If you just add it to the $PATH variable it will get fixed.

Edit the ~/.bashrc file in your home folder and add this line :-

export PATH=$PATH:~/npm

Here "npm" is the path to my global npm packages . Replace it with the global path in your system

Answer 6

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.
