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"

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 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 am new to Node Js and Webpack. I tried to start a project with module-loaders.
Firstly, I installed nodeJs and NPM and created a new directory called tutorial. I used the command prompt to cd into this directory and then ran the following command npm init and then installed webpack via npm using the command below :
npm install -S webpack
The 1st command installed webpack locally into the project under the 'node-modules' directory and I can run my project by doing this:
nodejs node-modules/webpack/bin/webpack.js
The problem with this is that I have to place my webpack.config.js file inside of this directory which I want to place in my project root.
One solution to this problem was to install webpack globally on my machine which I did using the command below :
npm install -g webpack
This installed Webpack and now I do have a Webpack command. However, this command does not seem to be working or doing anything at all. When I try to run this from my project's root directroy it does not do anything at all (See Screenshot)
Please tell me what I am doing wrong!!
webpack is not only in your node-modules/webpack/bin/ directory, it's also linked in node_modules/.bin.
You have the npm bin command to get the folder where npm will install executables.
You can use the scripts property of your package.json to use webpack from this directory which will be exported.
"scripts": {
"scriptName": "webpack --config etc..."
}
For example:
"scripts": {
"build": "webpack --config webpack.config.js"
}
You can then run it with:
npm run build
Or even with arguments:
npm run build -- <args>
This allow you to have you webpack.config.js in the root folder of your project without having webpack globally installed or having your webpack configuration in the node_modules folder.
You can run npx webpack. The npx command, which ships with Node 8.2/npm 5.2.0 or higher, runs the webpack binary (./node_modules/.bin/webpack) of the webpack package.
Source of info: https://webpack.js.org/guides/getting-started/
I had to reinstall webpack to get it working with my local version of webpack, e.g:
$ npm uninstall webpack
$ npm i -D webpack
npm i webpack -g
installs webpack globally on your system, that makes it available in terminal window.
The problem with my setup was webpack was installed but webpack-cli was missing
npm i -g webpack webpack-cli
If you prefer to install locally then install without -g flag
The quickest way, just to get this working is to use the web pack from another location, this will stop you having to install it globally or if npm run webpack fails.
When you install webpack with npm it goes inside the "node_modules\.bin" folder of your project.
in command prompt (as administrator)
go to the location of the project where your webpack.config.js is located.
in command prompt write the following
"C:\Users\..\ProjectName\node_modules\.bin\webpack" --config webpack.config.vendor.js
Installing webpack with -g option installs webpack in a folder in
C:\Users\<.profileusername.>\AppData\Roaming\npm\node_modules
same with webpack-cli and webpack-dev-server
Outside the global node_modules a link is created for webpack to be run from commandline
C:\Users\<.profileusername.>\AppData\Roaming\npm
to make this work locally, I did the following
renamed the webpack folder in global node_modules to _old
installed webpack locally within project
edited the command link webpack.cmd and pointed the webpack.js to look into my local node_modules folder within my application
Problem with this approach is you'd have to maintain links for each project you have. Theres no other way since you are using the command line editor to run webpack command when installing with a -g option.
So if you had proj1, proj2 and proj3 all with their local node_modules and local webpack installed( not using -g when installing), then you'd have to create non-generic link names instead of just webpack.
example here would be to create webpack_proj1.cmd, webpack_proj2.cmd and webpack_proj3.cmd
and in each cmd follow point 2 and 3 above
PS: dont forget to update your package.json with these changes or else you'll get errors as it won't find webpack command
Actually, I have got this error a while ago. There are two ways to make this to work, as per my knowledge.
Server wont update the changes made in the index.js because of some webpack bugs. So, restart your server.
Updating your node.js will be helpful to avoid such problems.
I am new to nodejs and gulp stuff. I working on a nodejs project in which I have to run jslint on all the files. I am using gulp for this purpose.
My problem is that In order to run gulp on cli I don't want to install gulp globally and also does not want to update my path variable, So I have installed gulp and other node modules in my project locally using the package.json file
cd myproject
npm install
Since I don't want to install gulp globally and want to run the local gulp I have added script in my package.json file like this as given in this question
{
"name": "",
"version": "1.0.0",
"main": "index.js",
"private": true,
"dependencies": {
"async": "1.5.0"
},
"devDependencies": {
"gulp": "^3.9.0",
"gulp-jslint": "^0.2.2"
},
"scripts": {
"gulp": "./node_modules/.bin/gulp" // is this correct?
}
}
Add added a gulpfile.js inside my myproject folder
var gulp = require('gulp');
// include plug-ins
var jslint = require('gulp-jslint');
// JS hint task
gulp.task('lint', function() {
gulp.src('./common/srp/*.js')
.pipe(jslint())
.pipe(jslint.reporter('default'));
});
gulp.task("default", ["lint"]);
But now on my command line inside myproject folder, when I run gulp and gulp lint I get an error
user1-VirtualBox:~/myproject$ gulp lint
/usr/local/node-v0.10.26-linux-x64/bin/gulp No such file or
directory
Its looking for gulp in the global node module.
Is there a way to make gulp run on cli without installing globally and updating PATH variable.
Any help will be appreciated
Thanks
You can find any executable installed by npm in node_modules/.bin. So you can run gulp locally using:
./node_modules/.bin/gulp
You can find more information at no command 'gulp' found - after installation
With your code you should be able to run command
npm run gulp
Please try
One way to define script is
"scripts": {
"gulp": "gulp"
}
If in case you are not able to run gulp command in your project, run
npm link gulp
It will link your global install gulp with your local project. Then try
gulp -v
If it is showing you the version then you are done. Now you can run any gulp command as you want.
Scripts defined in package.json are accessed through NPM, i.e. npm run-script gulp. I imagine you're trying to run plain old gulp, which should fail since you didn't install it globally.
The scripts section won't automatically create an alias, which I think is your mistake here. You could define one yourself or create a simple bash script if you don't want to type it every time.
Try:
path_to_node path_to_gulp_js gulp_task
Example:
node\node.exe node_modules\gulp\bin\gulp.js build
Like #snorberhuis said. The only way for me to get gulp to work globally was to call gulp manually
I am building in a Jenkins environment
Execute Windows Batch Command
cd your-app
npm install gulp
Execute Windows Batch Command
cd your-app\node_modules\.bin
gulp
Just another alternative that will work locally but will give you global like feeling.
Add to your shell config i.e. ~/.bash_profile the following
export PATH=$PATH:./node_modules/.bin
you have to source that file, execute rehash or just open a new shell and then gulp (and any other script inside that folder) shall be available as a global command.
The way I did this after bashing my head every possible place is simply going to your Application and install npm dependencies like this:
1- E:\webra-jenkins\Code\trunk\WebRa.Web>npm install
Once npm installed then go this directory
2- [%Application_path%]\node_modules\.bin
And execute the gulp and give your file/task, like this:
3-[%Application_path%]\node_modules\.bin>gulp gulpfile --tasks
In my case as I saw the following lines... I got the inner happiness
18:06:36] Working directory changed to [%Application_path%]
[18:06:37] Tasks for [%Application_path%]\gulpfile.js
Now you can run your tasks 1 by one.
[%Application_path%]\node_modules\.bin>gulp pack-vendor-js
Check in your project node_modules/.bin folder and make sure gulp is in there. I had a case where it wasn't there that I never tracked down the reason for. If it isn't there, try re-installing gulp locally and see if it shows up. If that doesn't work and you get tired of the problem, the gulp-cli package will fix it for sure, but that shouldn't be something you have to do.
The simplest solution I know of is to use npm bin:
`npm bin`/gulp ...
This keeps you away from hard-coding any paths.
Nothing was working for me. I followed all instructions from everyone. No matter what I did I could not run the Gulp commands.
To fix this I opened the Node.js command prompt that comes installed automatically when you download and run node.js.
Once I was in this command prompt I could run the following commands:
npm install -g gulp
gulp -v
This is probably a matter of common knowledge but as someone starting out no one suggested to run the node.js command prompt and install gulp from there. Everything I read talked about regular powershell or command prompts with elevated permissions.
Globally install gulp in C:\Users\%USERNAME% using this command
npm install –g gulp
You can install any other gulp methods you need to use.. Ex:
npm install -g gulp-concat
npm install -g gulp-uglify
npm install -g gulp-replace
Then at the directory you wish to use GULP. Open the command prompt (Shift + RightClick) then install locally and you'll be able to execute gulp.
npm install gulp
You can install any other gulp methods you need to use.. Ex:
npm install gulp-concat
npm install gulp-uglify
npm install gulp-replace
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.
