gem install timetrap error

[parasew]

Parsing documentation for timetrap-1.15.1
Before reporting this, could you check that the file you're documenting
has proper syntax:

/Users/foob/.rvm/rubies/ruby-2.6.2/bin/ruby -c lib/Getopt/DelimScanner.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

(NoMethodError) undefined method `[]' for nil:NilClass

ERROR: While executing gem ... (NoMethodError)
undefined method `[]' for nil:NilClass

Exactly the same here..
just with version 2.6.1

[JiProchazka]

It's a bug in RDoc. Don't know how to workaround though

[jostber]

It's the same result with Ruby 2.6.3.

[jostber]

This works though:

gem --no-document install timetrap

[andreskytt]

gem install -N timetrap in 3.0.3

[brarnaudovski]

The problem comes from rdoc gem and it has a fix in version 6.2.0

Unfortunately this version comes as a default only in ruby 2.7

You can use @jostber 's solution (by using --no-rdoc option) or you can gem install rdoc which fill fetch the lates rdoc version.

My first suspicion was in the syntax of the lib/Getopt/DelimScanner.rb file. The error suggestion is:

Before reporting this, could you check that the file you're documenting
has proper syntax:

  /Users/branko/.rbenv/versions/2.6.5/bin/ruby -c lib/Getopt/DelimScanner.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

But running ruby -c lib/Getopt/DelimScanner.rb doesn't report any errors:

~/projects/timetrap master
❯ ruby -c lib/Getopt/DelimScanner.rb
ruby: warning: shebang line ending with \r may cause problems
Syntax OK

@samg You may consider adding some info/instruction in the Readme file for this. I can make a PR if you are OK with it.

@brarnaudovski feel free to make a PR if you still think it's needed
