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

I'm just starting out, I need to set up a source code on my machine.

node -v v12.16.1 npm -v 6.13.4

can you help me resolve this error when I run the npm install command ( on Windows 7 Entreprise SP1 64-bit)

I don't know which of these did the trick or if it was a combination, but this worked for me after trying so many other answers.

I opened a command prompt as administrator in Windows, and I ran the following command.

npm install -g @angular/[email protected] --unsafe-perm --force

Thanks for all the problem solved following the addition of the --force option

npm i -g @angular/cli --force

Try installing angular-cli with --unsafe-perm flag. In Windows, it might be permission issue while installing postinstall.

ou must check whether any previous version on Agnular is installed (or even partially) on your computer. If so, then run command:

npm uinstall @angular/cli

Then clean the npm cache by this command: npm cache clean --force

Now, try to re-install Angular by the command: npm i -g @angular/cli The current version of Angular is 9.1.3 so you don't need write it in the command.

Here -g command is used to install Angular globally.

For everything to work fine, please close all IDE (if being used) then perform above oprations.
