I want to 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.
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".
Single line solution
In terminal
npm install -g --force nodemon
There is a problem with integrated terminal of vs code. when I try in external terminal nodemon works. But in integrated terminal, it gives bash: nodemon: command not found error.
so here is my solution
install nodemon as development dependency
npm install --save-dev nodemon
and change package.json of the project
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"nodemon": "./node_modules/.bin/nodemon"
},
to run nodemon type into terminal in project folder
npm run nodemon
Mine was I went to Control Panel and Repair the NodeJS app and tried to install again with npm install -g nodemon and now it works. Maybe you mixed up or something with Node.
check out here :-
npm install -g nodemon
and then run
$nodemon server.js
You won't need to install nodemon anymore, since Nodejs has finally introduced its --watch feature which restarts the process when an imported file is changed.
node --watch index.js

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
On Windows, I was having issues installing nodemon directly from the Command line. Downloaded Cygwin and I was able to npm install nodemon instantly.
You can add path to node packages in System Path variable.
Add "C:\Users\UserName\AppData\Roaming\npm".
Even after adding path to System Path variable it did not work for me using nodemon. Then i used npm run serve to run the server. now it is up and running. Btw i am a windows user
This command worked for me.
If your global installation didn't work then install it in your
development dependency.
npm install --save-dev nodemon
Updated
After Path settings we also need to type in the following commands
Set-ExecutionPolicy Unrestricted
what this command enables running scripts on the system
I think some of us can't reach global environments without admin privileges.
If you tried everything and it's still not working, try running VSCode as administrator. It worked out for me.
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.

I'm using Node.js and npm for the first time, I'm trying to get Vite working, following the tutorials and documentation. But every time I run into the problem 'vite' is not recognized as an internal or external command, operable program or batch file. I have been trying to find a solution for 4 hours now but with no results.
I tried restarting pc, reinstalling node.js, several procedures to create vite project but in vain. I suppose it's my beginner's mistake, but I really don't know what to do anymore.
Commands and responses I run when I try to create a vite project:
npm create vite#latest
>> my-portfolio >> vanilla & vanilla
cd my-portfolio
npm install >>resp: up to date, audited 1 package in 21s found 0 vulnerabilities
npm run dev
resp:
> my-portfolio#0.0.0 dev
> vite
'vite' is not recognized as an internal or external command,
operable program or batch file.
try to install the packages to make it work
npm install or npm i
For this error use the following command on your terminal in the present working directory of the project
npm install
npm run dev
first, try to install a node package manager and then run npm run dev hope it will work
yarn add vite
on project folder to add vite,
and run
npm run dev
again.
remember to update your node version to 18, LTS from 17 might not support this installation.
update:
I try to fresh install again my Laravel 9.19, since i had update my node to version 18, npm install & npm run dev just work fine without yarn.
According to documentation https://vitejs.dev/guide/#community-templates
npm install
npm run dev
npx vite build
I found myself in the same situation.
The problem is vite.cmd is not in the system or user PATH variable, so it cannot be found when it is executed from your project folder.
To fix it, you should temporarily add the folder where vite.cmd is in your PATH variable (either for the entire system or your user). I recommend adding it just for your user, and keep in mind you should probably remove it after you stop working on that project, because this could affect future projects using the same build tools.
To do this:
My PC > Properties > Advanced system settings > Click on Environment Variables (alternatively just use the start button and begin typing Environment, you should get a direct link)
On "User variables" find "Path" and edit it.
Add a new entry for the folder where vite.cmd is. Example "C:\dev\reactplayground\firsttest\test01\node_modules.bin" Check your project folder to find the right path.
Make sure your close and open your console for this change to affect.
Go back to your project root folder and run "vite build", it should work now.
for me I've:
1 - excuted yarn add vite
2- and then npm install
work fine !
For me I had a project I created on one computer and it had this in devDependencies:
"vite": "^3.1.0"
I did pnpm install and it reported everything was fine, but I was getting the error. I ran pnpm install vite and it installed it again with this:
"vite": "^3.1.8"
After that it worked fine. So try using npm, yarn, or pnpm to install the vite package again and see if that works.
try npm install
then npm run build
Recently faced this error and I run
npm install
npm run dev
then the output was
VITE v3.2.4 ready in 1913 ms
THAT'S COOL 😎😎😎

You need Node version 15 or higher, I had the same problem because I was using an older version of it.
Needs to install all the packages in package.json and run again
npm i
npm run dev
For me this worked:
I changed NODE_ENV environment variable to development ( earlier it was production - which should not be the case, as dev-dependencies won't get installed by npm install or yarn )
Here is what to make sure before running npm install or yarn:
Make sure `NODE_ENV` environment variable is not set to `production` if you running locally for dev purpose.
'vite' is not recognized as an internal or external command, operable program or batch file.
> vite
'vite' is not recognized as an internal or external command,
operable program or batch file.
try to install the packages to make it work
npm install or npm i
The following works just fine!
npx vite build
npm i
npm run dev
I had the same challenge and I was finding the error
create-vite : command not found
I resolved by running the command:
npm i create-vite
From there you can continue with running the command:
npm create vite#latest
Reference:
https://www.npmjs.com/package/create-vite
npm install or npm i
helps with issue of 'vite' is not recognized
After I tried npm install
i could run the npm run dev after and it showed me the localhost
When I run nodemon bin/www inside my app, it works perfectly, when I try to run nodemon app, it throws this error:
'\"node .\bin\www\"' is not recognized as an internal or external command,
operable program or batch file.
I believe this happened after I received a notification from nodemon today to run npm install -g nodemon to update the nodemon library, after the installation, I got this error:
Please try running this command again as root/Administrator.
I tried to run the cmd as administrator, again, the same problem. Any solution?
step 1: run npm install -g nodemon
step 2: verify installation npm list -g nodemon
Now you can run the app by two ways
nodemon ./server.js localhost 8080
Any output from this script is prefixed with [nodemon], otherwise all output from your application, errors included, will be echoed out as expected.
2nd just type nodemon
If you have a package.json file for your app, you can omit the main script entirely and nodemon will read the package.json for the main property and use that value as the app.
With a local installation, nodemon will not be available in your system path. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as npm start) or using npx nodemon.
or
It turns out that you don’t have to run the command again as
Administrator, and doing so won’t fix the problem. Try
npm cache clean first.

I think you are getting this error because you did not install it as a global module. Try to install nodemon using the -g flag.
$ npm install -g nodemon
Install the nodemon module globally using
npm install -g nodemon
Also install the module in the package in your project where the package json is present using
npm install nodemon -save
Check if the nodemon is present in the json list.
Now run the js file using any of the following
nodemon
nodemon app.js
nodemon app
Use the following command line in an windows environment (1st cd to your apps root directory):
nodemon ./bin/www
I wanted to know how to use nodemon, and push it to a git repo, and have other developers on the project be able to use nodemon without having to run the command npm install -g nodemon. Ideally, I would like all developers on the project to be able to just run npm start and nodemon is called whether or not it's installed globally. I've already run npm install --save-dev nodemon, and I'm mostly curious if there is a way to get nodemon to be run from within node_modules, in my start command in the scripts section of the package.json file.
If you install it locally, i.e. without the -g flag, it's available in ./node_modules/.bin/nodemon. So just configure that path in your npm start script.
For example:
"start" : "./node_modules/.bin/nodemon app.js"
I am working with npm on a web app and I found an issue when using some packages that requires terminal commands to run such like nodemon and concurrently
I installed it via
sudo npm install --save-dev nodemon
and when I try to use it via:
nodemon ./server.js
I get an error
nodemon command not found
and the same when I used concurrently
I tried also with
sudo npm install --save nodemon
and it doesn't work.
it only work if I installed it globally
sudo npm install -g nodemon
Why I can't use it when install locally?
Note: I can found the executable file at node_modules/.bin
but this following not working as well
node_modules/.bin/nodemon ./server.js
Global packages can be launched directly because they are saved in your PATH directory by default. If you saved a package locally you can see it on node_modules/.bin/ as you mentioned. So there are 2 ways to achieve what you want if you want to run an executable package if installed locally:
You can run it via terminal as ./node_modules/.bin/nodemon yourscript.js
Or via npm scripts in your package.json file, you do this:
{
"scripts": {
"nodemon": "nodemon yourscript.js"
}
}
and execute npm run nodemon.
The 2nd approach works for both packages installed globally or locally.
I prefer installing packages locally, so my other apps won't get affected especially if I'm using different package versions per project.
UPDATE
On npm#5.2.0 onwards, it comes with a binary called npx. So you can run specific packages on the terminal just by npx [package] and it executes either your local or global npm package. In your case it should be something like npx nodemon server.js.
Because it's in your node_modules/.bin folder, not your PATH.
You can either use ./node_modules/.bin/nodemon or $(npm bin)/nodemon to call nodemon.
To run any locally installed npm module (Mocha, Eslint, Nodemon, etc.), you can now use npx. Try npx nodemon server.js.
I also recommend setting main within your package.json to point to the script you want to run (index.js by default), so you could just run npx nodemon or nodemon (if globally installed) and it will know which script to run.
This is because the local node_modules folder is not in your PATH. See the link to the duplicate question for more details.
I've tried uninstalling and and reinstalling nodemon several times both locally and globally with:
npm install -g nodemon
(tried it both with and without sudo)
and it seems to install no problem, and gives me:
/usr/local/bin/bin/nodemon -> /usr/local/bin/lib/node_modules/nodemon/bin/nodemon.js
/usr/local/bin/lib
└── nodemon#1.11.0
but whenever I run
nodemon server.js
in my app, I get;
-bash: nodemon: command not found
Like I mentioned, I've tried the same process but installing locally to my app dependancies, but it doesn't seem to make a difference. What's going on here? I followed the same process on a different machine, and it worked no problem.
Googling around, I came across some posts that mentioned changing/adding the PATH? But it's not clear to me if that's or the problem or what that means.
Also, other globally installed npm modules run just fine
nodemon is not being found by bash.
Edit your ~/.bash_profile file and add:
PATH=$PATH:/usr/local/bin/bin/
Start a new shell to see it work, or run source ~/.bash_profile to have it apply to the current session.
Instead of using sudo switched as root and then just run:
$ npm install -g nodemon
sudo su -
export PATH=$PATH:/home/USER/npm
npm install -g --force nodemon
# THESE LINES + START FROM A NEW TERMINAL...
# IN MY CASE
npm install -g --force node-inspector
