Dependency errors when setting up build environment

[isigmund]

I am trying to setup a build environment as described in CONTRIBUTING. When I run npm install I get unsatisfied dependencies:

Binary is fine; exiting.
npm ERR! peerinvalid The package eslint does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer eslint-config-esnext@1.6.0 wants eslint@~3.4.0

Is there something wrong with the package.json ? Any help on getting this resolved is appreciated

Take care Ingo

I think you might need to update your nodejs and npm versions, eslint is node 4+

i have the same issue but with node v4:

 npm start

@HubertusH I am not sure you are having the same issue at all, no mention of Sonos here :)

[isigmund]

@digiltd You were right. I had a totally outdated version installed via apt-get. So after removing the old version I used this to get node 4.6:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 68576280
sudo apt-add-repository 'deb https://deb.nodesource.com/node_4.x precise main'
sudo apt-get update 
sudo apt-get install nodejs

so after this npm install worked. I still got one dependency problem though:

ingo@OpenHab2:~/org.openhab.ui.habpanel/web$ npm install
npm WARN package.json habpanel@1.0.0 No README data
npm ERR! Linux 4.2.0-42-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "install"

npm ERR! peerinvalid The package eslint-plugin-react-native@1.2.1 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer eslint-config-recommended@1.5.0 wants eslint-plugin-react-native@~2.0.0

npm ERR! Please include the following file with any support request:
npm ERR!     /home/ingo/org.openhab.ui.habpanel/web/npm-debug.log

but apparently it did not prevent me to run bower install and gulp successfully.

So many thanks take care Ingo

Glad it is working, as I am sure you have noticed npm can easily turn in to a messy nightmare. I am currently working on an Ember project and after running npm install I now have a node_modules folder that is 107mb and has over 600 folders in the first level.

I am not sure if Habpanel (which is Angular based) even uses React (which in turn uses the ES/Babel combo).

There is an eslint task in the gulpfile, but that might be a left over from a boilerplate or previous project the gulpfile was based on.

[ghys]

Glad it's working too! The eslint part is there because I intended to use it some day, but never got around to actually do it :)

@isigmund if you intend to submit a PR with an added dependency, I'd appreciate it if you could announce your intentions first; the reason I ask is, I'd like to review it beforehand because we need to stabilize the size of the external code (already at ~650k minified now) and don't add too many libraries for isolated use cases. Thanks and happy hacking ;)

[isigmund]

@ghys I am working on a new widget to show an analog clock on a panel. I'm going to use http://deepu.js.org/angular-clock/ so there is some new dependencies that I need for that. I will create an enhancement issue to track this. Once I am ready I will create a PR.

[ghys]

Ok, I saw your post in the openHAB community forums. angular-clock looks small enough and the widget could be a welcome addition. Try to avoid linking to the Syncopate font on Google's CDN, in fact try to avoid it at all and use the Roboto font.
