Undefined method `empty?' for 3.1:Float (NoMethodError)

[nvzqz]

I'm trying to generate docs for RandomKit and I get this error:

$ jazzy --source-directory ../RandomKit --config .jazzy.yaml

Using config file /Users/nvzqz/dev/projects/swift/RandomKit.gh-pages/.jazzy.yaml

Here's my Ruby version:

$ ruby --version

ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin16]

Thanks!

Looks like setting swift_version in the config file does not work any more, whether or not the version has a dot in it. Not a ruby version issue.

It does works from the command-line (--swift-version) so I hope that will do for a workaround.

I think it needs to be a string rather than a number, try quoting it?

[nvzqz]

@segiddins quoting it worked. It worked for me previously without quoting it. Something might've changed since then. The last time I generated the docs was June 1st.
