npm install doesn't create node_modules directory

I am trying to do a homework for a mongodb uni course. They gave us some files, instructions are:

run npm install mongodb then node app.js

for some reason npm install does not create a node_modules directory but I don't see any build errors:

mongo-uni/hw1-2$ npm install mongodb

See @Cesco's answer: npm init is really all you need


I was having the same issue - running npm install somePackage was not generating a node_modules dir.

I created a package.json file at the root, which contained a simple JSON obj:

{
"name": "please-work"
}

On the next npm install the node_modules directory appeared.

npm init

It is all you need. It will create the package.json file on the fly for you.

NPM has created a node_modules directory at '/home/jasonshark/' path.

From your question it looks like you wanted node_modules to be created in the current directory.

For that,

  1. Create project directory: mkdir <project-name>
  2. Switch to: cd <project-name>
  3. Do: npm init This will create package.json file at current path
  4. Open package.json & fill it something like below

    {
    "name": "project-name",
    "version": "project-version",
    "dependencies": {
    "mongodb": "*"
    }
    }
    
  5. Now do : npm install OR npm update

Now it will create node_modules directory under folder 'project-name' you created.

I ran into this trying to integrate React Native into an existing swift project using cocoapods. The FB docs (at time of writing) did not specify that npm install react-native wouldn't work without first having a package.json file. Per the RN docs set your entry point: (index.js) as index.ios.js

As soon as you have run npm init and you start installing npm packages it'll create the node_moduals folder after that first install

e.g

npm init

(Asks you to set up your package.json file)

npm install <package name here> --save-dev

installs package & creates the node modules directory

For node_modules you have to follow the below steps

1) In Command prompt -> Goto your project directory.

2) Command :npm init

3) It asks you to set up your package.json file

4) Command: npm install or npm update

If you have a package-lock.json file, you may have to delete that file then run npm i. That worked for me

my problem was to copy the whole source files contains .idea directory and my webstorm terminal commands were run on the original directory of the source
I delete the .idea directory and it worked fine

For me, I had to go into the directory where the package.json is itself and then run npm install in order to see node_modules folder. Apparently, running npm install in a directory that has NO package.json does not error or tell you otherwise.

A few things to try that worked for me:

  1. Try running the NPM install from outside of your IDE, just from the bash / PowerShell / cmd prompt. It will work the same, and might complete successfully.

  2. Try upgrading NPM:

npm install -g npm

or, to stay within a specific major version:

npm install -g @latest-7

THEN run your npm install again.

cd into the directory and then run

npm install node

This answer is for users like my students who named their windows account name with unicode characters (other than a-z) :) They placed their project folder on their desktop folder.

Please make sure that your project folder path doesn't include special characters such as "ÇŞİ " etc..

In our case, moving folder to C:\ fixed the problem.
