@sonuk85184451 

Just hit the following command in ui.frontend module 

npm cache clean --force

I hope this will resolve the issue.

Thanks & regard,

This error is related to relative paths.

Use the following npm package dependency to resolve the issue

https://www.npmjs.com/package/tspath

@sonuk85184451 Please cal you tell me more, i have the same problem urix and resolve-url. I downgraded in version 3.10.8 but still can't run gulp command.

Thank you

@lediona - can you please share the error what you are getting now ?

[BrijeshYadav]

After this npm cache clean --force

You also need to remove node_modules under ui.frontend module
