Gulp error (module not found) - node.js

I have installed npm locally according to an article (I don't remember the URL). So that my npm packages are in ~/.npm-packages/. So gulp is in ~/.npm-packages/bin/gulp and this is a link: gulp -> ../lib/node_modules/gulp/bin/gulp.js
When I run which gulp I got /home/victor/.npm-packages/bin/gulp
When I go to the bin directory and run gulp like ./gulp.js -v I can see it works. However, when I run gulp globally I got such error:
module.js:338
throw err;

So gulp is trying to find modules in /usr/lib, but why? Why not in my home directory? I have all these modules in ~/.npm-packages/lib/node_modules/gulp/node_modules
I'm absolutely confused and can't get gulp working. I've tried to reinstall it with the same effect.

This is what I did to solve the problem:
cd /usr/lib/node_modules/gulp/node_modules/v8flags
sudo node fetch.js
And that's it. The last instruction will create the required file.

This is what I did to solve the problem:
sudo npm install gulp && sudo npm install --save del && sudo gulp build

Removed npmlog folder and now I can't use npm

I'm a beginner in linux and npm in general, at first I screwed my npm installation by doing this :
npm conig set prefix usr/bin/env
I really don't know what I was really doing here, but then I got an EExist error whenever I run npm .
I decided to remove npm and node via :
sudo apt-get remove npm
sudo apt-get remove node
And the reinstalled them normally via the apt-get command . I had the same error, so I did a very immature thing and I deleted all folder containing the word npm, and more importantly npmlog, uninstlled and reinstalled node and npm via apt .
Now I'm having this error that I couldn't fix whenevr I use the npm command .
module.js:340
throw err;

I tried reinstalling, removing other npm folders in node_modules, but none of those techniques worked for me, please how can I fix this ?

Please help me fix this error?
update your npm
$ npm install npm -g
I would try to update/install NPM
$ npm update -g npm
I know the answer!
Uninstall nodejs.
Delete all references to npm and nodejs (Program Files, Program Files(x86).
Then also delete those in AppData/Roaming (npm and npm-cache to be sure).
Reinstall nodejs.
It works!

Getting error: Cannot find module 'errno' running node script

I've just installed a fresh copy of Ubuntu 15.10, node 4.2.2 and npm 2.14.7 (with nvm) on a new machine. I have installed webpack and webpack-dev-server globally and installed my project dependencies with npm i.
Now when I try to run my node server I get the following errors:
module.js:339
throw err;

Any suggestions please?
Node.js searches for modules in the ./node_modules/ directory in the path where the program is.
For example if you script is here /home/user/scripts/somescript.js you should have /home/user/scripts/node_modules/.
Just do npm install errno in here /home/user/scripts/.
It seems that something had gone wrong with my npm install and my project dependencies were only partly installed. Just running npm install again didn't fix it. I did an npm cache clean, removed my node_modules directory and then ran npm install again. The problem was then resolved.

Getting koa to work (nodejs web framework)

I am running Deepin and trying to get koa to work. There is little documentation on the subject.
I did the following as stated on koajs.com:
$ npm install -g n
$ n 0.11
$ node --harmony my-koa-app.js
I recieve the error:
➜test-koa-app$ sudo node --harmony test-koa-app.js

As Mike Kamermans mentioned in the question comments, to use a module in a node application, it must first be installed in the project directory.
To install it, run npm install koa in a terminal in your project folder.
If you've run npm init and setup a package.json file in your project, you can add the --save flag and save a record of the dependency with npm install --save koa.
Version 2 of koa now out. Go here:

node.js returns "Cannot find module 'lockit-mongodb-adapter'"

I am going through my first node.js project. I've installed lockit , have a app.js file, and when I try to run it I get this error
module.js:340
throw err;

I am quite certain I have lockit-mongodb-adapter installed.
You need to install the module. Cd to the root of your app directory and run this command and make sure lockit-mongodb-adapter is in your node modules directory.
npm install lockit-mongodb-adapter
Another thing you can do if you are certain it is installed is double check to see what is installed by running this command:
npm list
And this one to see what is installed globally:
npm list -g
Update:
I was able to reproduce the issue you where having. And to resolve it I deleted the module from the node moules directory. And re-installed with the following command:
npm install lockit-mongodb-adapter -save
It now shows up in npm list with no issues:
