ARM architecture not supported about lnd-explorer

[bmancini55]

I'll take a look at it today and see if we can come up with a solution. Thanks for submitting the issue!

I am unable to reproduce this problem on a clean system.

I'm using an Odroid-XU4 (same CPU as HC2) with a fresh install of the Ubuntu server image provided by hardkernel + latest updates applied, kernel version 4.14.5-92.

Installed build-essential & git from default apt sources, installed nodejs 8.9.4 from nodesource using install scripts (https://nodejs.org/en/download/package-manager/), cloned lnd-explorer and ran npm install && npm run build && npm start

I verified that [email protected] is installed and working properly and verified that the complied app.css is accessible on the webserver.

Can you provide any other information and/or try running npm rebuild node-sass?

I just tried again. With npm rebuild node-sass I get the error message that "python" or "python2" could not be found in the path. Not sure what packages (apt or npm) to install, or just to set the path correctly...

My config:
Linux kernel 4.14.20-108
Node.js v8.10.0

When trying the build again:

$ sudo npm run build

You need to have python in order to build node-sass.

Can you run python --version and/or which python and ensure it is installed and that the path is correct? The odroid I'm using for testing has Python 2.7.12 installed.

[Stadicus]

Sorry for the lack of any response, I am heavily focused on my Raspberry Pi project at the moment and currently do not have a running Odroid setup. Please bear with me, I will pick this up again. Thanks for your patience!

[jsgoyette]

For what it's worth, I ran into this problem on an Odriod and was able to get it working by manually making the changes included in this yet merged pull request for the node-sass repo:

https://github.com/sass/node-sass/pull/2253/files

[Stadicus]

On a new try, it actually worked on the Raspberry Pi with the following commands:

$ git clone https://github.com/altangent/lnd-explorer
$ cd lnd-explorer
$ npm install
$ npm audit
$ npm audit fix
$ npm run build
$ npm start
