SOLVED: Incorrect integrity when fetching from the cache

Last updated on 18 Jul, 2022

I was trying to install the dependencies of an existing project using:

yarn install

All of a sudden I saw this error in terminal:

...
[2/4] Fetching packages...
error Incorrect integrity when fetching from the cache

The solution to this problem is to do a cache cleaning. Just run following command from the same position:

yarn cache clean

After running above command, we can proceed with yarn install or yarn add commands. It should work fine.
