Extension fails to install on latest coc.nvim

Update: it seems that a different version of Node.js is being selected than I expected, according to the contents of :CocOpenLog shown below:

This StackOverflow post suggests that this type error with Inversify can be fixed by installing the reflect-metadata package. I will try entering the .config/coc/extensions/node_modules, attempt to install the package using yarn, and see if it works.

[ebkalderon]

Unfortunately, it didn't work. I still receive the same error:

In fact, I'm now seeing another error in the statusline that wasn't there before:

[coc.nvim] engine coc & vscode not found in /Users/eyalkalderon/.config/coc/extensions/node_modules/reflect-metadata/package.json

I think I am going to completely uninstall and reinstall coc.nvim.

[ebkalderon]

Okay, I suspect I know what is happening. I am using the Nix package manager to manage my toolchains on macOS, including yarn. According to NixOS/nixpkgs#48705, it appears that the package provided for yarn in Nixpkgs is pinned to Node.js 8, instead of using whatever Node version is present in the environment.

To confirm whether this is really the problem, I will completely uninstall coc.nvim and then run:

nix-shell -p '(yarn.override { nodejs = nodejs-11_x; })' -p other-coc.nvim-system-deps-here

Once the environment is loaded up, I will attempt to reinstall coc.nvim and coc-python and see if that fixes the issue.

[ebkalderon]

Well, it doesn't appear to have fixed the problem. It resulted in no change, even after completely removing the ~/.config/coc directory and the plugged/coc.nvim directory and reinstalling. Looking into the coc.nvim source code, it appears that the package.json specifies the following targets anyway:

"targets": [
  "node8-linux-x64",
  "node8-macos-x64",
  "node8-win-x64"
]

So I think the Node.js version discrepancy here is a red herring, because yarn installed via nix-env is already pinned to Node 8 anyway. Not really sure how to proceed from here. @chemzqm, do you have any ideas?

[ebkalderon]

Hmm, I noticed that when I run :CocInstall coc-python, there is a warning message by yarn that actually looks relevant because the type error is occurring in the inversify package:

warning: coc-python > [email protected]: Re-Released as 5.0.1

Can anyone reproduce?

[chemzqm]

(/snapshot/coc.nvim/lib/util/factory.js:67:32)

it means you're using binary release, call coc#util#build() to fix it.

[robjuffermans]

Hi, I've got the same issue. Using nvm.

[chemzqm]

https://github.com/neoclide/coc.nvim/wiki/F.A.Q#how-to-use-cocnvim-from-master-branch

Checkout :h g:coc_node_path if you're using nvm.

[ebkalderon]

@chemzqm Awesome, call coc#util#build() fixes the problem! Thank you. I'm assuming the binary release will be fixed as well on a later date?
