error: undefined method `*' for nil:NilClass

[kim-em]

Under Ruby 1.9.3 (with pdf-reader downgraded to 1.1.1), I get

$ pdf-extract extract --references example.pdf

error: undefined method `*' for nil:NilClass. Use --trace to view backtrace

Under Ruby 1.9.1 (again with pdf-reader at 1.1.1), I get

$ pdf-extract extract --references example.pdf

error: undefined method `sort_by!' for #<Array:0x007fa62e9cc930>. Use --trace to view backtrace

Any suggestions? I'm not sure what else to try, but am excited to get pdfextract running!

Under Ruby 2.0.0, with pdf-reader downgraded to 1.1.1, it looks like it works!

@semorrison Hi! Sorry about replying on this topic again. I'm trying to run pdf-extract. For some PDF papers it runs very well, but some I get these errors with a blank output :

• error: undefined method []' for nil:NilClass. Use --trace to view backtrace and
• error: undefined method *' for nil:NilClass. Use --trace to view backtrace

I'm using Ruby 2.0.0 and pdf-reader 1.1.1. Do you know can I solve this?
