Error: EACCES: permission denied when trying to install ESLint using npm
node.jsMacosNpmEslintnode.js Problem Overview
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?
node.js Solutions
Solution 1 - node.js
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.
Solution 2 - node.js
This problem is well documented in the [npm docs: Fixing npm permissions][1].
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

Solution 3 - node.js
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
Solution 4 - node.js
sudo npm install -g --unsafe-perm=true eslint
is sufficient.
Solution 5 - node.js
Use sudo before tns and it is work for me
Example:
sudo tns create Tekmo --template tns-template-hello-world
if I have used sudo then not found error like to create postinstall.js > Error: EACCES: permission denied
Solution 6 - node.js
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.
Solution 7 - node.js
For MAC user provide the access permission to project directory folder
- Right click on project directory folder
- Select get info
- Provide the access permission - Apply to inclosed items
Solution 8 - node.js
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.
