Describe the bug

If I try to install a new extension with CocInstall coc-java i get following message in new buffer (using mini.vim):

Install finished
- ✗ coc-java getaddrinfo EAI_AGAIN registry.npmjs.org

Navigating to the second line gives a modal with following message:

Using npm from: /usr/bin/npm
Get info from https://registry.npmjs.org/
getaddrinfo EAI_AGAIN registry.npmjs.org

I am not sure since when this bug appeared. It could be after I removed/reinstalled node/npm (ubuntu 20.04). It seems to be related to the network, but npm install works fine (I am behind corporate proxy with proxy configured), for example npm install -g neovim.

I have already reinstalled coc.nvim, node/npm. I tried removing everything node related to have a fresh installation, did not help.

Since I have this problem only with coc, but (apparently) not with node in general (or any other neovim plugins), I kindly ask if you have an idea what I could look at to tackle this issue.

Reproduce the bug

Since it did work some time ago, I am pretty sure this is not reproducible for others. I must have screwed something up.

EAI_AGAIN is a DNS lookup error. Can your dig registry.npmjs.org or ping registry.npmjs.org works?

[JSamir]

They both don't work. As I understand it dig does not work if you are behind a proxy (which I am).
dig:

If anything node-related would not work I would kind of understand it, but as of now I only have problems while installing coc extensions.

Installing node neovim provider (npm install -g neovim) uses the same mechanism as coc does for the installation of the extensions right? If yes, why does it work for npm at all if it is a general issue with dns?

[fannheyward]

CocInstall will fetch extension package from registry.npmjs.org, this is why it failed for you.

You can use vim-plug to install extensions: https://github.com/neoclide/coc.nvim/wiki/Using-coc-extensions#use-vims-plugin-manager-for-coc-extension

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

@fannheyward

I still have this issue, even in a freshly installed VM. I still use a proxy, but that is not an issue in any other apps.

Please note that in the last answer I mentioned that npm itself has no problems, only while issuing CocUpdate it does not work. It is still the same.

Details:
Through some other script I got some coc extensions installed in the folder ~/.config/coc/extensions. I removed that plugin but it left the extensions there. So when I use CocUpdate, it tries to update those extensions, but fails with a timeout (that's how I discovered it by accident).

If I navigate to this directory and try to update this extensions with npm update, it works. Installing new extensions works too. So for me this does look like a Coc issue.

The error has changed (as I said I have a new VM now), for example CocInstall coc-html:

Install finished

- ✗ coc-html Request timeout after 10000ms

If I hover over the last line:

Using npm from: /usr/bin/npm
Get info from https://registry.npmjs.org/

With npm it works:

I had the same problem and just adding the manual ip worked for me.

Try with that:

echo "104.16.17.35\tregistry.npmjs.org" >> /etc/hosts

And then try to install again.

You can use other registries according to :h coc-extensions-npm:

To customize npm registry for coc.nvim add coc.nvim:registry in your
~/.npmrc, like:

coc.nvim:registry=https://registry.mycompany.org/
