ldodds / dowl Goto Github PK

Pasted from console.
I'm not a ruby developer ... Is this a pre-requisite ?

% sudo gem install dowl

Ialso tried the other way :

should also support equivalentClass/property too

Just need to delete line 5 of bin/dowl:

https://github.com/ldodds/dowl/blob/master/bin/dowl#L5

Description: Can't apply context unless initialized with data supporting contexts
Version: a6551ec11d7ecff760bc22584e8dac7fe2904c68

Steps that will reproduce the problem?

1. sudo gem install -V dowl
2. dowl path/to/file.ttl

What is the expected result?
New HTML file.

What happens instead?

/Library/Ruby/Gems/2.0.0/gems/rdf-1.1.4.3/lib/rdf/model/graph.rb:126:in `initialize': Can't apply context unless initialized with `data` supporting contexts (ArgumentError)

    from /usr/bin/dowl:23:in `load'
    from /usr/bin/dowl:23:in `<main>'

Possible workaround:
?

Any additional information:

The code dies with an error if there isn't a foaf:name property on every author.
