How to fix npm throwing error without sudo?
If you are encountering errors when trying to run npm without using sudo, it's likely related to permission issues. Running npm with sudo can lead to problems with file ownership and permissions, and it's generally not recommended.
Here are a few steps you can take to fix npm permission errors without using sudo:
Change npm's Default Directory
Change npm's default directory to a directory you own:
# Create a directory for global installations in your home folder
mkdir ~/.npm-global
# Configure npm to use the new directory
npm config set prefix '~/.npm-global'
# Add the following line to your profile or rc file (e.g., ~/.bashrc, ~/.zshrc)
export PATH=~/.npm-global/bin:$PATH
# Restart your terminal or run `source ~/.bashrc` (or the appropriate rc file)
Fix npm Global Package Installation
If you have installed global packages using sudo, you might need to change ownership of the related directories. Replace username with your actual username.
sudo chown -R $(whoami) ~/.npm-global
sudo chown -R $(whoami) /usr/local/lib/node_modules
Uninstall Global Packages Installed with sudo
Remove global packages installed with sudo:
sudo npm ls -g --depth=0 | awk -F/ '/node_modules/ && !/\\/npm$/ {print $NF}' | xargs sudo npm -g rm
Reinstall npm Packages Locally
If you're having issues with a specific project, navigate to the project directory and reinstall the npm packages:
rm -rf node_modules
npm install
Use a Node Version Manager (NVM)
Consider using NVM to manage your Node.js versions. NVM allows you to install Node.js versions without requiring elevated privileges and helps avoid permission issues.
Follow the instructions on the NVM GitHub repository: https://github.com/nvm-sh/nvm
After performing these steps, you should be able to run npm without using sudo and resolve permission-related issues. Always be cautious when using sudo with npm, as it can lead to problems with file ownership and permissions.
