Error: EACCES: permission denied when trying to install ESLint using npm

Question

I'm trying to install ESLint with npm by going:

npm install -g eslint

However I get the following error:

Deans-Air:~ deangibson$ npm install -g eslint

And to be honest I get this every single time I try and install something with npm. Sometimes using 'sudo' works, sometimes it doesn't... How can I fix this once and for all?

Use --unsafe-perm=true and --allow-root flags with npm install like below:-

sudo npm install -g eslint --unsafe-perm=true --allow-root

it worked like charm for me.

If it's a local package obviously don't use g. It can have a big effect on the result – maudulus Jan 31 '20 at 17:46

This works on `macos`. Maybe it's unsafe, but it's the only solution that worked for me. – loretoparisi Feb 02 '21 at 14:39
It not unsafe to use it actually, coz installing npm modules globally requires you to use sudo, reason is it creates files in root directories – DHRUV GUPTA Feb 03 '21 at 15:21
This alone did not help in my case, had to use ```-i``` flag as well with sudo. – Akshay May 17 '22 at 07:03

This problem is well documented in the npm docs: Fixing npm permissions.

You have 2 solutions available:

Option 1: Change npm's default directory to a hidden directory in your home folder

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH
source ~/.profile

Option 2: Use a package manager that takes care of this for you

brew install node

Option 2 worked well but I utilized the ~/.npm directory as my dotfiles had already configured that location (but I forgot!) – Ken Prince Jan 10 '17 at 06:54
upvoting for option 2. I should have done this a long time ago :sweat-smile: – Micah Stubbs Sep 17 '17 at 23:37

If you use option one, you might end up with this problem, so I don't recommend this at all: https://askubuntu.com/questions/452860/usr-bin-sudo-must-be-owned-by-uid-0-and-have-the-setuid-bit-set#471503 The root user should own /user/bin – Joe Eifert Nov 27 '17 at 00:27

Option 4: Install using Yarn with `sudo yarn global add ` – Andre Feb 13 '18 at 15:29

Do no use option 1, it will ruin your sudo. – Germán Barletta Jul 18 '18 at 14:28
@GermánBarletta I used option 1, how do i fix it, please help? – Shivansh Singh Sep 11 '18 at 20:01
ugh, sorry to hear that @ShivanshSingh, I followed the suggestions that appear on the link that Joe shared. Don't worry, it's easy to fix. https://askubuntu.com/questions/452860/usr-bin-sudo-must-be-owned-by-uid-0-and-have-the-setuid-bit-set#471503 – Germán Barletta Sep 12 '18 at 21:17
how to do the option 2 in linux? specifically in debian? – Nuwan Karunarathna Dec 07 '18 at 03:52
Option 2 was the right answer. – binarydreams Aug 26 '22 at 22:06
Option 2 is great. Using sudo to install NPM dependencies seems wildly dangerous to me. – Perry Feb 19 '23 at 22:28

Running the following command solved the issue for me while installing my packages.json :

 sudo npm install --unsafe-perm=true --allow-root

To install only the package which caused the issue:

  sudo npm install -g --unsafe-perm=true --allow-root eslint

for MacOS users having this issue!

while starting the react server, write sudo npm start not npm start.

That solved the issue for me.

you can login as root using sudo su. First run the command sudo su on your terminal, then give your login password. Finally execute your expected command npm install -g eslint. It works for me.

This is a simple permissions error and one of the ways to resolve it is to simply delete the node_modules folder and run npm install again, making sure you are not the root user.

Just had the same error while running

npm install -g @ionic/cli native-run cordova-res

To fix, run the following

sudo apt update
sudo apt upgrade -y

I had read the already present solutions but thought there was something else, UNSAFE isn't a safe keyword, lol. While running the command with the --unsafe-perm=true, I noticed it downloading what seemed to be update binaries. So, I updated and tried again.
