Nothing happens on MarkdownPreview

Thanks for this plugin!

When I run MarkdownPreview on a .md in neovim v0.3.4 nothing happens for me after I install this plugin and I’m not sure how to debug it.

I have installed the package with dein and use the default config from the Readme.

Running checkhealth produces,

health#mkdp#check
========================================================================
  - INFO: Platform: linux
  - INFO: Nvim Version: NVIM v0.3.4
  - INFO: Node version: v10.15.2

  - INFO: Script: /home/rth/.cache/dein/repos/github.com/iamcco/markdown-preview.nvim/app/server.js
  - INFO: Script exists: 1
  - OK: Using node

and I also have tried adding the following to .config/nvim/init.vim

let $NVIM_MKDP_LOG_FILE = expand('~/mkdp-log.log')
let $NVIM_MKDP_LOG_LEVEL = 'debug'

but this file is not created. Same thing happens (i.e. nothing) when I set,

let g:mkdp_auto_start = 1

and try to edit/save markdown file.

Is there any other things I should try to debug it (or log files that I can look at)? Thank you!

Edit: another possibly relevant information is that

• I am using neovim on a remote Ubuntu 19.04 server.
• I can see that MarkdownPreview command is only available for markdown files, running it on any other file produces “E492: Not an editor command: MarkdownPreview”, so at least the file type detection is working.

@Unknown-Chinese-User do :call mkdp#util#install() again.

Running :messages listed a JS error cannot-find-module-tslib, leading me to believe an unstable build.

After I removed, reinstalled this plugin, and tested it with and without yarn, the issues was fixed for both cases.
