That was in VS Code editor.
The command line would be similar but I'll give it to ya.

Since I see that this version is different I went ahead and installed 2.6.1 this one and tests, and some examples work just fine. But I am now getting an error with the Rake task to install and s few others.
One is with the generated gemspec.
rake aborted!
ArgumentError: $SAFE=2 to 4 are obsolete
gnuplot.gemspec:1:in `block in parse'
Tasks: TOP => install => build
But again the gem at rubygems will suffice for me even though I learned a thing or two with this master.

2.6.2 failed but 2.6.1 passed?
