Ionic1 vesion 3.3 getting error.. when i am add plugin, platform

I am getting error when i am adding plugin cordova plugin add cordova-plugin-crosswalk-webview --save

and i am getting this error :-

cordova plugin add cordova-plugin-crosswalk-webview --save
:heavy_multiplication_x: Running command - failed!
[ERROR] Cordova encountered an error.
You may get more insight by running the Cordova command above directly.

[ERROR] An error occurred while running cordova plugin add cordova-plugin-crosswalk-webview --save (exit code 1):

Error: Cannot find module 'internal/fs'

and my cli is also show :- npm update check failed
Try running with sudo or get access │
│ to the local update config store via │
│ sudo chown -R $USER:$(id -gn $USER) /Users/sanjeevkumarraja/.config

No one have answer for this error…???

Well, your post is contradictory. You said you ran cordova plugin add cordova-plugin-crosswalk-webview --save in your first sentence, but then show an error message of running something in ionic .... Which is it?

Run the same ionic command but with --verbose added at the end.

Also: Your post is formatted very confusing: Please edit your post and use the </> button above the post input field to format your code or error message or wrap it in ``` (“code fences”) manually. This will make sure your text is readable and if it recognizes the programming language it also automatically adds code syntax highlighting. Thanks.

Did you do this?

yes, i am run this type :-
ionic cordova plugin add cordova-plugin-crosswalk-webview --save,
sorry for that…

and i am getting this type error in ionic v1 :-

Ionic is not ready for Node8 and Npm5 - so stuff will break.

You still didn’t edit your post to make it readable and not do anything of what I posted, so I will stop helping you for now.

Thanks,
i am trying anythings alse.
