npm install is missing modules

Question

Before I can run gulp in my project I need to run npm install. This works except on my computer, because I get the following error:

Err         


        

Answer 1

It seems that gulp need 'karma' dependencies (socket.io ,di ,log4js...) so you will have to run :

npm install karma

so just runing this command solved the problem, and all should be good, the same thing happens with grunt as well for some reasons.

Answer 2

This worked for me. By commenting 3 lines in C:\Program Files\nodejs\node_modules\npm\node_modules\graceful-fs\polyfills.js.

Answer 3

To resolve missing npm modules run:

sudo npm install -g npm-install-missing

Answer 4

I am using the same version of npm/node. Sometimes, it is like npm is "lost". What I suggest is :

• rm of your node modules (at least the one that is concerned)
• npm cache clean
• run "npm install" several times, until all dependencies are resolved and no message are displayed

Answer 5

I've faced the same problem when bootstrapping a MEAN application and add each missing dependencie with npm install packageName --save was not an option so I came across to npm-install-missing whom has saved my life :)

Installation

npm install -g npm-install-missing

Usage

npm-install-missing

Answer 6

Running npm install will install all dependencies that are specified in the package.json. Seems like you have quite a few dependencies that are not defined that way. Use npm install packageName --save and npm will add the package to your package.json.
