Issue while installing YARN

Question

I am trying to install YARN through npm. but I am getting errors.

By running

npm install --global yarn

I see the following:

  % npm install --global yarn                                                                                           !457
npm ERR! code EEXIST
npm ERR! path /usr/local/bin/yarn
npm ERR! EEXIST: file already exists
npm ERR! File exists: /usr/local/bin/yarn
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.

npm ERR!     /home/tripurjoshi/.npm/_logs/2023-03-22T07_06_33_396Z-debug-0.log

I am seeing the following results when i try to see the version of the yarn through

yarn --version

You just need to install corepack not yarn, the command is npm i -g corepack.

If still getting some erros, just install an older version of corepack, that solved for me!
