I've installed Node.js for Windows and I'm trying to install a package via npm. The command prompt is in the directory of the project (C:\Users\username\Desktop\NodeTest), which contains a single helloworld.js file. Upon typing 'npm install express', I receive the following error:
ENOENT: no such file or direcotry, open 'C:\Users\username\package.json
I'm attempting this from a clean install and cmd is running as admin.
Any ideas?
I was facing the same issue. I firstly delete my node_modules and delete the cache by following command:
rm -rf node_modules && npm cache clean --force
then I delete the package-lock.json file from my project and then hit npm install in command prompt and it works.
As already pointed out by Subburaj this is because you are missing a package.json.
Just run npm init to initialize that file for you; afterwards it should work.
If you are working on a Windows machine using Vagrant/VM, there's a chance that symlinks are the culprit for your problem. To determine if that is the case, simply copy your package.json and package-lock.json into a test directory that is not mounted/shared between OSs.
mkdir /tmp/symlinktest
cd {{your directory with your package*.json}}
cp package*.json /tmp/symlinktest
cd /tmp/symlinktest
npm install
If this results in a successful install, you'll need to either exclude the node_modules directory from the mount (there's various articles on doing this, however I can't say I've had success) or run npm install outside the mounted volume.
I deleted the package-lock.json and It worked for me.
Basically I was Offline while I tried to install with npm, so go online and try
npm install again
Check the project folder which you opened in microsoft visual code. Generally you are not in the right path so npm is not able to search the package.json ... My project was in Document/hostel/hostel .. I opened Document/hostel ... So npm tried to find the package.json in Documents folder .. When i entered one level inside to Document/hostel/hostel .. it was fixed.

I have been cloning repositories with node and MongoDB but I always run into issues running npm install when I cd into the folder directory.
It has to be me because I happens every time. What am I missing?
Seems like npm install is the 3rd step after 1: git clone "repository link", 2: cd in clone folder.
Please guide me in the right direction.
Thanks a ton
You can run npm install from a directory where package.json file is located since this is the one which holds all the info regarding packages.
So just try to make it sure that the directory from where you are firing npm install command, have package.json file.
Apart from this, just check if you have npm installed. Run npm -v
I'm currently trying to execute the command npm install to get all dependencies and modules necessary to run my package.json.
The problem is that I don't have Internet access to fetch from the internet, so I have downloaded the node_modules on a different PC and copy-paste it on my local folder that contains all. If I tried to run npm install without arguments, it's still trying to fetch from internet and fails.
I have read their documentation and apparently they have listed few npm install that takes different arguments, but still, I'm unable to install from the folder already downloaded.
I've tried to do npm install node_modules on the path that contains the package.json, but nothing. I'm running on windows 7.
If someone has an approach to specifying the local node_modules and just install all modules inside, I'll appreciate.
Thanks!
You probably should use npm-link...
From the docs:
Go to the node_modules directory, and, inside each package, run npm-link:
$ cd node_modules
$ cd package-name
$ npm link
$ cd ..
...
In the directory of your project which needs the local modules:
$ npm link package-name
When i try to install package on my local directory using npm install connect,but it just keep pop up some warning about
no such file or directory, open '/Users/felixfong/package.json'
But i don't not want to install package at my computer directory,i want to install at my local web app directory
Are you sure you are inside your local web app directory when you run the npm install connect command?
cd app-directory/
npm install connect
Also ensure that a package.json file is also present in the app-directory.
If it isn't present, you can use npm init command to create the package.json file interactively.
You have to go inside your project directory using
Then you can check package.json.
If package.json file is not there then initialize npm using the following command:
npm init
Then your can install the package using the following command:
npm install connect
'npm install connect' does not save the connect npm package in package.json file.
For saving the package into package.json file you have to givt --save option like:
npm install connect --save
Make sure that you are in web app's directory. Current path can be checked via command pwd in Linux and cd in windows. Navigate to your web app directory if you are somewhere else. Check existence of package.json by listing the content of the folder. ls and dir can be used for ubuntu and windows respectively for listing content. Commands for ubuntu are as below:
pwd
cd your-path/
ls
Now Initialize npm in your web app directory if package.json is not already existing there.
npm init
This will ask some information like:
name of the app,
its version,
description,
entry point,
test command,
git repo,
keywords,
author and
license (if any)
You can select default values by leaving the fields empty if you aren't sure or confused about any field. Combining this information as json, npm will create a file named package.json
Just run the desired command now after initialization of npm or if its already initialized:
npm install connect
I am writing a library and need to know what will happen if a user tries to run npm install -S X in their project before a package.json file exists.
I just tried this on Windows, and sure enough, NPM did not barf and went along with it's business but when the install command completed, there was still no node_modules folder nor a package.json file.
Does anyone know what is expected to happen? I assume I should require the users of my library to run "npm init" before running "npm install X" ?
Looks NPM does throw an error at the end of the install -
ENOENT: no such file or directory, open 'package.json'
but I wonder if that prevents the install process from create a node_modules dir, and actually putting the dependency in there.
npm install without the -g flag will walk up the folder tree checking for folders that contain either a package.json or a node_modules folder.
If either of those conditions are met, then that folder will be treated as the current directory for the purpose of the npm commands you are running. If no such folder is found, then the current folder is used.
As you noted, a node_modules folder will be created and after the package is loaded into the cache it will be unpacked into that folder.
I'm trying to test Gulp and I find this problem.
I installed Gulp globally with: sudo npm install -g gulp.
Then I was created the folder: mkdir my-gulp
cd my-gulp
And the I try to do this: sudo npm install --save-dev gulp
It seems work fine, no errors, but my folder my-gulp continues empty.
I can see in console, this line:
gulp#3.8.6 ../../node_modules/gulp
And I thinkig the problem is here "../../", I think it must be "gulp#3.8.6 node_modules/gulp"
What do you think? Maybe is something about $PATH?
First, you should never run npm via sudo for local packages. (In fact, you shouldn't run it as root ever, but that's a different, more complex issue to solve.)
Second, you need to initialize NPM before you can install packages. It sounds like you didn't do this.
There's two ways:
If you have an existing package.json, which contains the required information about a project, you can copy it into your folder, then edit in a text editor of your choice to get started. If the package.json includes existing dependencies, you can either remove them, or run npm i in the folder to install them.
If you are starting fresh, run npm init to set up a new package.
Once you have a valid package.json, you can install packages into your application.
As to why you are seeing ../../gulp, I'm guessing you have a package.json further up the file tree somewhere.
