Unable to install coc-prettier

When I try to install coc-prettier via let g:coc_global_extensions, I get this error:

I debug the npm log and I found this

Don't know what's wrong with your npm.

I've had a similar issue. I solved it as follows:

1. Downgrade npm to version 4.6.1: npm install -g [email protected]
2. Open nvim and run: :CocInstall coc-prettier

That's all!

@Mikhael1729 That npm is way too old.

@Mikhael1729 That npm is way too old.

Previously to that indicated version, I tried with npm version 5.10.0, I think perhaps, a version between 4.6.1 and 5.10.0 works well too. I need to try!

Perhaps a newer version works well. I need to try it.

IDK but this issue comes with only npm. If you do this it will work.

Plug "neoclide/coc-prettier", { do: "yarn install --frozen-lockfile" }

Plug 'neoclide/coc-prettier', { 'do': 'yarn install --frozen-lockfile' }

use single quotes in everything if you're using vim-plug
