[Pranomvignesh]

What / Why

When I tried installing a recently updated package ... I am getting an error like this

npm ERR! code EINTEGRITY
npm ERR! sha512-VXJ7jSkaONZFcAb9PzpwCb4kv60SMMPhbljvso9muXH4/cx3jaxC0lVk+DUcalaUPkWZzaUhggJhs5EqJMiovg== integrity checksum failed when using sha512: wanted sha512-VXJ7jSkaONZFcAb9PzpwCb4kv60SMMPhbljvso9muXH4/cx3jaxC0lVk+DUcalaUPkWZzaUhggJhs5EqJMiovg== but got sha512-mqE42GAVzFwCQQjO428cEuOPATV1EZ5uzARBWScng6sCawbualjMatgPiu9149OsVn6OzJL0F3Lk1KwsmOjR5Q==. (4767924 bytes)

I tried all the methods from stackoverflow

Still i am getting the same issue

How

I created a new folder and tried installing the package with empty cache but i still throws error

I have hidden package name and local registry name as it is private

This is the log file's output
