Error: Unable to install Angular on WSL due to permission denied for Node

Struggling to set up angular on WSL2, with node version 17.3.1 and npm version 8.3.0 already installed. Received an error when trying the command npm install -g @angular/cli:

npm ERR! code 127

npm ERR! path /root/.nvm/versions/node/v17.3.1/lib/node_modules/@angular/cli

npm ERR! command failed

npm ERR! command sh -c node ./bin/postinstall/script.js

npm ERR! sh: 1: node: Permission denied

npm ERR! Full log of this run can be found at:

npm ERR! /root/.npm/_logs/2022-01-18T09_06_05_078Z-debug-0.log

Any ideas on how to resolve this?

Answer №1

Make sure to execute the command with sudo npm. In Ubuntu, running it with root permission is necessary based on how you installed node.

Consider cleaning your npm cache beforehand

npm cache clean

or

npm cache verify

After that:

npm install -g @angular/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="66050a0f265e4855">[email protected]</a> --unsafe-perm=true --allow-root

Answer №2

After encountering a chain of errors, I successfully resolved my issue by completely uninstalling and then reinstalling the Windows Subsystem for Linux (WSL). It was a drastic solution, but it ultimately solved all my problems. Thanks to everyone for their support.

Answer №3

Encountering a similar problem on Ubuntu 20.04 WSL.

Following the installation of WSL, it's advisable to close the terminal and retry.

It is possible that you lack the necessary permissions for writing on npm packages.

To resolve this, attempt a reinstall using 

sudo npm install -g <package-name>
