I think something is broken with pgfutter on OSX. I had to install from source before I could run it at all (issue #48). Now when I try to import a CSV, all I get is a single comma:
$ ~/go/bin/pgfutter csv ./test.csv
,
$ ~/go/bin/pgfutter csv ./foo.csv
,
test.csv is a real CSV file. foo.csv doesn't exist. Either way, it just prints a comma to the console and exits.
pgfutter is a really cool concept, and looks very helpful. Hope this is easy to fix.
