Jekyll installation, wrong number of arguments

Help
1

Hi,
I have trouble installing jekyll on fedora. I created an issue on stack overflow but then found this discourse.

I am running Fedora 28. I have all the dependencies mentioned on installation page.

ruby -v
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

gem -v
2.5.2

bundle -v
Bundler version 1.16.1

When I try to install Jekyll, I am getting this -

gem install jekyll
ERROR:  While executing gem ... (ArgumentError)
    wrong number of arguments (given 1, expected 0)

Running as root doesn’t help either. When I run backtrace,

gem install jekyll --backtrace
ERROR:  While executing gem ... (ArgumentError)
    wrong number of arguments (given 1, expected 0)

I guess the ruby version was the problem. Once I installed ruby 2.4 using https://rvm.io/ installation was successful
