I get the error: "[coc.nvim] build/index.js not found, please install dependencies and complie coc.nvim by: yarn install"

I was wanting to try out a autocompletion tool for python for vim, so I decided to install coc for vim, so I installed by going into my .vimrc file and adding

call plug#begin(~/.vim/plugged')

Plug 'neoclide/coc.nvim', {'branch': 'release'}

Plug 'neoclide/coc.nvim', {'branch': 'master', 'do': 'yarn install --frozen-lockfile'}

call plug#end()

but I just get the error

I get the error: "[coc.nvim] build/index.js not found, please install dependencies and complie coc.nvim by: yarn install"

So I tried installing yarn by visiting their website

yarnpkg.com

and I went to the installation page

https://yarnpkg.com/getting-started/install

I followed all the steps correctly, I had the node.js version v17.8.0 and I just get this error:

I had no idea what just happened so I went on with the next step
