EACCES: permission denied, unlink

First of all, you need to check permission by running the command:

ls -la ~/.config/yarn/global/node_modules/.yarn*

I received the next response:

-rw-r--r-- 1 root staff 15163 Jul 18 15:17 ~/.config/yarn/global/node_modules/.yarn-integrity

Then if you saw that root had permission, but you don't have, you should add permission to yourself:

sudo chown -R ${USER} ~/.config/yarn/

You change permission settings at the bottom of the Info window for a file, folder, or disk in the Finder. For example, you can change permission settings for a folder so that other users who log in to your Mac, or connect to it for file sharing, can view but not change files in a folder.
