Develop Reference

I am new to this and having issue while runing the java script

Can someone help. I am completely new to this but when I am running the script I am getting below error. if someone can teach me or help me it would be a great help

run this in your terminal
alias firebase="`npm config get prefix`/bin/firebase"
or you just install firebase tool globally
npm install -g firebase-tools
either of them should do the trick,

What i tried:
completely removed node and NPM and installed.
sudo chown -R $(whoami) ~/.npm
by following the answer from here: npm throws error without sudo
Note:
I tried to install globally is working. But installing locally is not working.
I tried both sudo and normal user.

try sudo npm install even if you are working on sudo user

Use the latest npm
npm install -g npm

ReactJS + NodeJS: What is error "Pass --update-binary to reinstall or --build-from-source to recompile"?

I transferred a ReactJS + NodeJS project from another computer to a new computer. Then inside the folder, I did npm install in the terminal but getting the following response back.
> fsevents#1.0.14 install /Users/Joshua/Projects/practice_project/node_modules/fsevents
> node-pre-gyp install --fallback-to-build
[fsevents] Success: "/Users/Joshua/Projects/practice_project/node_modules/fsevents/lib/binding/Release/node-v46-darwin-x64/fse.node" already installed
Pass --update-binary to reinstall or --build-from-source to recompile
And on the previous computer, I ran the project via npm run server, but when I do it after npm run server in the project on the new computer, now I am getting:
> practice_project#1.0.0 serve /Users/Joshua/Projects/practice_project
> nodemon server/server.js --ignore components
sh: nodemon: command not found

I looked around but can't seem to find the right solution. Tried npm install -g node-gyp but getting tar.unpack untar error.
What could be the issue? Will upvote and accept the answer. Thank you.

In this case, the first message you received is just telling you it's attempting to rebuild the fsevents package for your environment, then realized it already had it built, so stopped the process.
The second message is indicating that you are attempting to run nodemon but it isn't installed. I would hazard a guess that it was installed globally on your previous machine (and therefore not included in the project's package.json). If you want to install it globally again, you'll need to run npm i -g nodemon.

npm config permission error

I am having permission problems with the npm config command. It seems that for some reason it is trying to change the owner of my ~/.npmrc file. When running npm config set color false, I get the following error:
npm ERR! Error: EPERM, chown '/home/bamboo/.npmrc'
npm ERR! { [Error: EPERM, chown '/home/bamboo/.npmrc'] errno: 50, code: 'EPERM', path: '/home/bamboo/.npmrc' }

The file .npmrc has the right permissions and I can edit it manually but I need to do it from the npm config command since it is part of an automated build. I can't seem to find valuable information on that matter. I set the prefix to a directory I own and can install globally without any problem but can't run configure! I am running Ubuntu 14.04.
Does anybody have some ideas?

I had the same problem.
https://github.com/npm/npm/issues/7563
Turns out changing from sudo su to sudo su - when starting the bamboo agent process solved the problem.

Got this problem once.
The .npm directory does not have sufficient permissions. Run the following command:
sudo chown -R $(whoami) ~/.npm

Yeoman Javascript error involving 'mkdir'

I'm setting up a Meanjs instance with a Yeoman generator. When I do 'sudo yo meanjs' everything works fine until it looks like it is trying to make a directory and it fails, any ideas on what is going on here?

That is a pretty common error.
Yeoman is running the following:
bower install & npm install
Bower install succeeded, however NPM install is failing because of user permissions. Just run:
sudo npm install

The ZenCoder's answer is spot on, but if you want to permanently fix this permissions error, you can follow the tutorial at: https://docs.npmjs.com/getting-started/fixing-npm-permissions
Since you're on a Mac, you could actually avoid npm permissions errors altogether by just installing node instead via homebrew:
brew install node (this will install npm too)
Homebrew installs programs to a directory that doesn't require sudo for write, so you can npm install -g <whatever> freely without it.
