Environment info

I am using Bash on Ubuntu on Windows

node -v
v15.12.0

npm -v
7.6.3

Steps to reproduce

I did everything as root user:

First I tried
npm install -g @vue/cli

But this returned an error
npm WARN deprecated urix@0.1.0: Please see https://github.com/lydell/urix#deprecated
npm WARN deprecated har-validator@5.1.5: this library is no longer supported

Than I tried npm install -g --unsafe-perm @vue/cli but this also gave me the same error

After that I tried this but that didn’t worked also. npm config set user 0 npm config set unsafe-perm true

At least I tried npm install vue npm cache clean --force npm install -g @vue/cli

But this also returned the same error.

What is expected?

Install Vue CLI

What is actually happening?

Getting an error.

Hi, It looks like your NPM global bin directory is under some user permission privileges (root/sudo). NPM global dir path: npm list -g | head -1

Try using sudo:

sudo npm install -g @vue/cli

I used the following commands to firstly update the version of npm I was using, uninstalling older versions of vue cli and re-installing the latest vue cli.

npm install -g npm npm uninstall vue-cli -g npm i -g @vue/cli

These steps seemed to work for me. Hope its helpful to others with this issue 🤘
