npm install doesn't create node_modules directory

Question

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
npm WARN package.json path@0.4.9 path is also the name of a node core module.

Answer 1

npm init

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

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

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

eg

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

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

Answer 7

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

Answer 8

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.

Answer 9

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进入目录然后运行

npm install node

This answer is for users like my students who named their windows account name with unicode characters (other than az) :) 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.

Answer 12

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
