Installing Add-ons Works Again

Dear Orange users, Some of you might have an issue installing add-ons with the following issue popping up: xmlrpc.client.Fault: <Fault -32601: 'server error; requested method not found'> This is the result of the migration to a new infrastructure at PyPi, which provides the installation of add-ons.

Writing Orange Add-ons

We officially supported add-ons in Orange 2.6. You should start by checking the list of available add-ons. We pull those automatically from the PyPi, which is our preferred distribution channel. Try to install an add-on by either: writing “pip install ” in the terminal or from the Orange Canvas GUI. Select “Options / Add-ons…” in the menu. Everything should just work. Writing add-ons is as easy as writing your own Orange Widgets or Orange Scripts.

The easy way to install add-ons

The exact mechanism of distribution of add-ons has changed significantly in the last year to simplify the process for add-on authors and to make it more standards-compliant. Among other things, this enables system administrators to install add-ons system-wide directly from PyPi using easy_install or pip.
