I get the error message above when I try to download Yarn, not sure what to make of it. Any suggestions for how to successfully download Yarn? Looks like I may be missing some part of the setup. Thank you!

try to run your command with sudo e.g. sudo npm i -g corepack

[mattaereal]

Hi! Please don't use sudo or administrative privileges, there's no need.

It appears the default path for a local installation (or prefix) is not set properly, that's why it's complaining about permissions.

Will you please show me the output of the following command?
↪ cat ~/.npmrc

In advance, you can modify the contents of that file, to this
prefix=/home/<your_username>/.npm-packages

Or just run this and try again the installation command from the beginning:
echo "prefix=/home/andrewverbinnen/.npm-packages" > ~/.npmrc

More info on this

Note: never run anything from someone you don't trust or if you don't know exactly what it does.

[averbinnen]

andrewverbinnen@Andrews-MBP ~ % cat ~/.npmrc
cat: /Users/andrewverbinnen/.npmrc: No such file or directory

^here's the output of the first command.

andrewverbinnen@Andrews-MBP ~ % npm i -g corepack
npm ERR! code ENOTSUP
npm ERR! syscall mkdir
npm ERR! path /home/andrewverbinnen
npm ERR! errno -45
npm ERR! ENOTSUP: operation not supported on socket, mkdir '/home/andrewverbinnen'

^I modified the contents of the file like you suggested and got the above.

What should I do now? Thank you for the help! Really appreciate it!

[mattaereal]

Uhm, something went wrong.

Please, paste again cat ~/.npmrc to show me.

[averbinnen]

andrewverbinnen@Andrews-MBP ~ %  cat ~/.npmrc
prefix=/home/andrewverbinnen/.npm-packages

Sorry, better?

[mattaereal]

I'm guessing you want to install corepack globally, and not locally. Would you re-execute the command with --verbose at the end to see where it fails?

[averbinnen]

how would I install corepack globally?

[othaime-en]

its normally using the -g flag. It's already in your npm i -g corepack --verbose command

[averbinnen]

So as an update, the sudo command worked. Needed to work in the terminal as an admin. Thank you!

[othaime-en]

Hey @averbinnen Mark the answer so that it can help someone else in future. Glad it worked out in the end.

[themalaysianguy]

This is awesome, i went through the same problem and this solved it too. what does cmd 'sudo' do?

[mattaereal]

Please refer to my answer because this is not recommended or expected at all.

[adityabhattad2021]

I guess for Node.js >=16.10 you just need to do

corepack enable

and then try

yarn --version
