As written in your post, this would appear to be an issue with npm rather than Node-RED

Which version of npm are you using (npm -v)?

What does
ls -l /home/alps/.npm
show and what user are you running under?

Don’t know if this is of any help but by chance I installed NR on my Mac (in addition to a previous installation on RPi3/DietPi) just last night, and decided to try it the Homebrew way on the latest Mac OS X, and got this exact error now and again when installing a bunch of nodes needed in an imported flow. Just a retry of the install button in NR installed them without anymore errors though.

Does that give an access error in the log too?

You didn't answer my question about which user you are running node-red as. I see you are using systemd, post the systemd startup script, which, unless you have written your own will probably be /lib/systemd/system/nodered.service

i did follow the following step : -

sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/nodered.service -O /lib/systemd/system/nodered.service
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-start -O /usr/bin/node-red-start
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-stop -O /usr/bin/node-red-stop
sudo chmod +x /usr/bin/node-red-st*
sudo systemctl daemon-reload

Then i did add the user in systemd as per instruction in website

I see you are using a non-recommended version of nodejs (11.x). The recommended versions are 8.x or 10.x. Whether that would cause that problem I don't know. Also you have not answered the question I asked earlier, what version of npm are you using
npm -v
You should be on version 6.x or above I think.
The recommended way of installing/upgrading node-red and the associated tools on a pi is in the link below. My recommendation would be to uninstall nodejs (I am not sure what the install script will do with a newer version than recommended) then run the upgrade script. That will make sure everything is consistent. If you still have problems then at least we are all starting on the same page.

Isn't this installed on a PC?

I agree it started with saying it was a new PC, but the install steps posted suggest that it is using Raspbian. Unless the same scripts are used for both. I think @tramanah needs to tell us what OS he is running on.

i did the following steps and manage to deploy successfully.

sudo apt-get purge nodejs

than

bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
  Stop Node-RED                       βœ”
  Remove old version of Node-RED      βœ”
  Remove old version of Node.js       βœ”
  Update Node.js LTS                  βœ”   Node v10.15.3   Npm 6.4.1
  Clean npm cache                     βœ”
  Install Node-RED core               βœ”   0.20.3 
  Move global nodes to local          -
  Install extra Pi nodes              βœ”
  Npm rebuild existing nodes          -
  Add shortcut commands               βœ”
  Update systemd script               βœ”
                                           

Any errors will be logged to   /var/log/nodered-install.log

All done.
  You can now start Node-RED with the command  node-red-start
  or using the icon under   Menu / Programming / Node-RED
  Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880
