It fails:

Add the puppeteer dependency to your project to resolve.
Run the following: npm install -g puppeteer
it seems npm can't access/find globally installed package puppeteer

Why is npm uninstall -g not uninstalling a package?

Local uninstall doesn't help either:

What's the reason of this problem?
I installed node by nvm.
Command line modules are installed in a project at ./node_modules/.bin so you can run eslint directly with ./node_modules/.bin/eslint. The better approach is to create a script entry in your package.json:
"scripts": {
"lint": "eslint"
}
because running commands from the scripts entry in package.json will automatically add ./node_modules/.bin to the path. This way you can run your lint with npm run lint
Did you try installing eslint globally?
npm install -G eslint eslinta#1.0.0

Does anyone know how to go about fixing that? If you manually install then you have to do that on every update.
Also, I can't find a place to report the bug...
I just had to run npm install --save kerberos mongodb to successfully install mongodb in my project. I assume you can do it globally as well, but there may be other issues.
From the mongodb NPM package docs:
The kerberos package is a C++ extension that requires a build
environment to be installed on your system. You must be able to build
node.js itself to be able to compile and install the kerberos module.
Furthermore the kerberos module requires the MIT Kerberos package to
correctly compile on UNIX operating systems. Consult your UNIX
operation system package manager what libraries to install.
It goes on to offer the following steps for diagnosing the issue on UNIX-based operating systems:
If you don’t have the build essentials it won’t build. In the case of linux you will need gcc and g++, node.js with all the headers and python. The easiest way to figure out what’s missing is by trying to build the kerberos project. You can do this by performing the following steps.
git clone https://github.com/christkv/kerberos.git
cd kerberos
npm install
If all the steps complete you have the right toolchain installed. If you get node-gyp not found you need to install it globally by doing.
npm install -g node-gyp
If correctly compiles and runs the tests you are golden. We can now try to install the mongod driver by performing the following command.
cd yourproject
npm install mongodb --save
If it still fails the next step is to examine the npm log. Rerun the command but in this case in verbose mode.
npm --loglevel verbose install mongodb
This will print out all the steps npm is performing while trying to install the module.
Other possible issues:
Your python installation might be hosed making gyp break. I always recommend that you test your deployment environment first by trying to build node itself on the server in question as this should unearth any issues with broken packages (and there are a lot of broken packages out there).
Another thing is to ensure your user has write permission to wherever the node modules are being installed.

Hello I recently tried installing grunt-command line interface according to the instructions on their website using the node package manager command
sudo npm install -g grunt-cli

I'm not sure how i update this dependancy. Can anyone shed any light on this?
Try the following:
npm cache clean
npm install -g npm (update npm)
reinstall node.js completely (if all fails).
Please let me know if this works.
Installing packages via npm shows the following message and nothing is installed..
sakthiganesh#ubuntu:~$ npm install express
express#2.3.8 ./node_modules/express

any solutions ?
Express are installed already in your case. By default npm installs modules in the node_modules subdirectory of the current dir. If you want to install module globally use commands with -g key:
sudo npm install -g express
But good practice are placing modules required for your application in the application directory. Go to directory, where your javascript file took place and run npm install without -g:
cd /var/www/my_app
npm install express
