npm install not working, can't install any of the node modules after cloning my project from git

I have cloned my project from git and when trying to do the npm install, it's not working.
I can't fix any of the errors - for example when trying to fix the core-js error with npm install --save core-js#^3 I still get the same message, that I need to upgrade.
Why is this happening? there were no errors before I cloned this repo?
npm WARN deprecated #babel/polyfill#7.12.1: 🚨 This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the #babel/polyfill docs (https://babeljs.io/docs/en/babel-polyfill) for more information.
npm WARN deprecated core-js#2.6.12: core-js#<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js#3.

Even I faced same kind of issue... might be this may be helpful to you.. :)
I have created a folder called "projects (Folder Name)" in that I have taken the clone of my project - called "xyz project (projects >> xyz project)"..
now by mistake I tried to install - npm install in "projects folder (parent folder)"..
but node modules have to be installed in "xyz project" (child folder)
So when I have used npm i... in xyz project... then node modules have installed SUCCESSFULLY..
Try this..

please, help me!!!

Please check your package.json - what is the "version" value? '0.1' is not a valid value, as it doesn't conform to the versioning scheme (http://semver.org/) npm packages uses. see https://www.npmjs.org/doc/json.html

nodejs npm install error, how to correct?

I am trying to do npm install on a project that requires 'ref' and I get this error. Any idea how can I correct this?
I have nvm runnning and node -v = 0.10.26
ref#0.1.3 install /root/node-ffi-libvirt/nodejs-usage/ffi-libvirt/node_modules/ref
node-gyp rebuild
gyp ERR! configure error

npm ERR! This is most likely a problem with the ref package,

npm ERR! Tell the author that this fails on your system:

npm ERR! You can get their info via:

npm ERR! npm -v 1.4.4

This suggests you don't have permission to create a directory.
It looks like the original project was installed as root (implied by the /root in the path) - so you must run the install as root as well.

try mkdir '/root/node-ffi-libvirt/nodejs-usage/ffi-libvirt/node_modules/ref/build' with the user you are running the command from. Fix that first and then run your command.

npm formidable install - getting errror

trying to install formidable JS library but having some install trouble,
it seems like https://registry.npmjs.org/formidable is down, and using isup.me, the registry site seems to be down completely = can anyone else confirm this as the problem or is it something that I am doing wrong on my side?

Try this:

It worked for me.

Now when I try and run
npm install jasmine-node -g
I get
-bash: /usr/local/bin/npm: No such file or directory
What's going on?

When you run npm install -g somepackage, you may get an EACCES error asking you to run the command again as root/Administrator. It's a permissions issue.
It's easy to fix, open your terminal (Applications > Utilities > Terminal)
sudo chown -R $USER /usr/local
** I strongly recommend you to not use the package management with sudo (sudo npm -g install something), because you can get some issues later **
Reference: http://foohack.com/2010/08/intro-to-npm/
** Update **
The reason is because this can cause permissions problems with lots of other apps, so I'd suggest not doing this.
A better solution when you are installing globally:
sudo chown -R `whoami` ~/.npm

Tried it myself.
You will need to install npm again. If you use git, this is the easiest way:
git clone http://github.com/isaacs/npm.git
cd npm
sudo make install
Otherwise, there is an install script too:
curl http://npmjs.org/install.sh | sh
(possibly you will need to use sudo sh instead of sh).
Then install your module again:
sudo npm install jasmine-node -g
EDIT 23/01/2014:
Now npm comes with NodeJs itself, so just reinstall NodeJs.

Look at the error
Please try running this command again as root/Administrator.
You need to run this with sudo
$ sudo npm install jasmine-node -g

This worked for me (OSX). I had to run it in my user directory.
cd ~
curl -L http://npmjs.org/install.sh | sudo sh

I was able to get around the permissions issues by setting my packages to install locally with a one-line "$HOME/.npmrc" file:
prefix=${HOME}/.npm_packages
