Issues when installing

[benji1000]

Hello,

I'm trying to install hack.chat on Ubuntu 16.04. Here is what I did:

sudo apt-get install nodejs npm
git clone https://github.com/AndrewBelt/hack.chat.git
cd hack.chat
npm install

And here is what I've got:

> bufferutil@1.1.0 install /home/ben/hack.chat/node_modules/bufferutil
> node-gyp rebuild

What am I doing wrong? Thanks for your help.

PS: I tried installing nodejs and creating a symlink for nodejs, and also nodejs-legacy. However, that did not change the situation. I think the problem comes from somewhere else.

[zeack]

try npm install as root

[benji1000]

Hello and thank you for your suggestion. However, it did not change a thing. I also tried uninstalling nodejs, npm, and cloning the repo into a new folder, while being a standard user, and then root. Still nothing.

I think it's problematic, because I don't have an "exotic" setup... just a Ubuntu Server 16.04...

Any other ideas?

[M4GNV5]

just try to run hack.chat, the errors are in an optional package. Even though i get those errors too hack.chat runs fine.

[AndrewBelt]

Running npm install shouldn't do anything different, and I wouldn't recommend it. It seems like an issue with bufferutil. Can you install it separately with npm install bufferutil?

[benji1000]

@M4GNV5: you were right, thanks! That's a non-blocking error.

@AndrewBelt: you were also right. Installing bufferutil separately displays an error stack trace similar to the one I got when running npm install only. Apparently, this is a common issue with this package that doesn't run well on some recent versions of node.js.

My problem is "resolved" (hack.chat is working despite the error), so thanks to the both of you!

FYI, I also got deprecation warnings when trying to install the client:

npm WARN deprecated jade@1.11.0: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated transformers@2.1.0: Deprecated, use jstransformer

Also, it seems that the command needs to be ran with sudo privileges, or else:

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/http-server
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/jade
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/less
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

Maybe this could be added in the install notes, since it doesn't say that it needs to be run with sudo.

[AndrewBelt]

I'd recommend installing global npm packages to your home directory rather than a root directory. Add

prefix=${HOME}/.npm

to your ~/.npmrc.

[benji1000]

You're right, that worked! I tried the procedure once again in my home directory, and didn't have the checkPermissions errors after I edited ~/.npmrc and then source ~/.npmrc.

I'm not familiar with nodejs, and maybe other users of your app are in this case too. Perhaps you could add a note about this in the documentation for hack.chat? Your call.

Thanks anyway!
