Error installing on Ubuntu 19.10

[akinsho]

Firstly this is such an amazing plugin 🚀 thanks for building it 👍

I've tried it on a macbook and it installs and works fine without any issues, but I tried installing it on a laptop using ubuntu 19.10 and I'm getting errors trying to install it.

[coc.nvim] Error on load extension coc-explorer from /home/username/.config/coc/extensions/node_modules/coc-explorer/lib/index.js: Error: Cannot find module 'trash'
Require stack:

- /home/username/.config/coc/extensions/node_modules/coc-explorer/lib/index.js

I went into the coc-explorer directory to try and see what happens if I add the trash module manually and I get

Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.

ERROR in Entry module not found: Error: Can't resolve './src' in '/home/username/.config/coc/extensions/node_modules/coc-explorer'

Not sure if this is the real underlying error or just a different thing. I've tried debugging this myself but I'm not very familiar with how coc extensions work, I'd appreciate any help

[weirongxu]

Try uninstall coc-explorer and reinstall it. if it still the same error, you can try to execute npm install trash --ignore-scripts in the coc-explorer directory.

[akinsho]

That worked 👍 @weirongxu, I ended up running npm install --ignore-scripts to get all the dependencies, since it wasn't just trash missing. Is there away to avoid having to manually install dependencies for this extension on ubuntu.

Looks like the webpack setup doesn't work on ubuntu for some reason 😕

[weirongxu]

I think it may be problems with your network, because I can't reproduce it on ubuntu.

It seems that prepare scripts will prevent install trash manually, I will remove it.

[akinsho]

@weirongxu just a heads up but this error seems to still occur so whenever I have to re-install this extension on ubuntu I still get the same error unless I use --ignore-scripts should there be a yarn install step at some point before prepare is run. Also I think npm no longer supports prepublish which is what commit 2221a5b changed this to

[weirongxu]

I still can't reproduce, this is my CocInfo

It maybe is an issue with how my npm/yarn is installed, although I haven't had any issues with anything else 😕

[weirongxu]

It's weird 😥, Did you configured .npmrc?

My npm version:

# npm --version
6.12.0

[akinsho]

My version is 6.12.1 I haven't changed my .npmrc
One thing that is a little confusing is that the webpack command fails because the entry point is missing. When I check the contents of /home/username/coc/extensions/node_modules/coc-explorer/ most of the files in this repo aren't there. There is no webpack.config.js no /src directory etc.

I'm not sure what the setup should be but looking at some of the other coc extensions they all have ./lib dir which I guess is where the typescript stuff is. I'm not sure exactly what is happening but I think the extension might not be getting setup correctly with all the files when I download it 🤔

EDIT: the directory for coc-explorer only contains an autoload dir, history.json, node_modules, package.json and a readme

[weirongxu]

There is no webpack.config.js no /src directory etc.

Because the published script has been compiled by webpack, the /src and /webpack.config.js is no longer needed.

[akinsho]

This might be me missing something but in that case should there not be a built version of the extension in the directory somewhere?, from what I can see there is no javascript file in the directory now

When I run npm install without --ignore-scripts I get the webpack error looking for the entry point 🤕

[weirongxu]

I only include there two directories..

coc-explorer/package.json

Lines 15 to 18 in 04f3384

	"files": [
	"lib",
	"autoload"
	],

The error you showing, should just be unable to install trash module

You're missing the lib folder..

Can you show me the package.json?

So weird, your package.json looks no any problem.

[akinsho]

Ah the reason I don't have lib directory is when I run CocInstall coc-explorer it fails with

## Messages
[coc.nvim] error: /home/akin/.npm/bin/npm install exited with 243, messages:
[coc.nvim] Installed extension: coc-explorer
[coc.nvim] Removed: coc-explorer
[coc.nvim] error: /home/akin/.npm/bin/npm install exited with 243, messages:
[coc.nvim] Installed extension: coc-explorer
[coc.nvim] Error on load extension coc-explorer from /home/akin/.config/coc/extensions/node_modules/coc-explorer/lib/index.js: Error: Cannot find module 'trash'

So I then went to /home/akin/.config/coc/extensions/node_modules/coc-explorer/ and ran npm i this seems to run the rimraf command which is what removes the lib dir. Straight after a clean CocInstall the lib directory is there it's just when it's reading lib/index.js the trash dependency is not there.

I'll try installing trash globally

[weirongxu]

I will use prepublishOnly to instead of the prepublish

[weirongxu]

😅 Sorry, I must use prepare to instead of the prepublishOnly, because some people use vim-plug to install the coc extension, prepublishOnly will break them.

[akinsho]

That's fine I looked at coc-go package.json and it uses prepare with some dependencies but those are installed correctly

This extension works correctly for me even though it uses prepare and has it's own dependencies

[gasull]

Try uninstall coc-explorer and reinstall it. if it still the same error, you can try to execute npm install trash --ignore-scripts in the coc-explorer directory.

I got the same error on Debian stable, but this fixed it. (I actually ran yarn add --ignore-scripts trash).

[weirongxu]

You can try npm cache clean --force.

[akinsho]

By the way this seems to have completely resolved for me 🤷‍♂️ I haven't had any issues at all (I'm now on Ubuntu 20.04) not sure if that makes a difference

[upsampled]

Confirming that npm cache clean --force fixed this issue for me as well
