'Failed at the @angular/[email protected] postinstall script

Hi I can't install the angular cli with npm install -g @angular/[email protected]. I keep getting this : 

> node ./bin/postinstall/script.js

module.js:549
    throw err;
    ^

Node version : 13.0.1
Npm version : 6.13.1
Ubuntu version : 18.04.2

I also tried without specifying a CLI version.

node.jsangularnpm


Solution 1:[1]

I tried with this command that I found online :

npm install -g @angular/[email protected] --unsafe-perm=true --allow-root

And it worked.

Solution 2:[2]

Try to run with sudo npm. On Ubuntu, you need to run with root permission. It depends on how you install node.

sudo npm install -g @angular/[email protected]

On the other hand, try to install node 12 and LTS versions to have a more secure version.

Hope it helps

Steps I followed

  1. Downgrade node version using nvm to v12.3.0
  2. Remove ng folder from /root/.nvm/versions/node/v12.3.0/bin
  3. Again do npm install -g @angular/[email protected] --unsafe-perm=true --allow-root

and it worked

Try clean your npm cache before npm cache clean or npm cache verify then npm install -g @angular/[email protected] --unsafe-perm=true --allow-root
