Hello, I am a Sketchup developer. When I run the code in ruby console in Sketchup "Gem::install("kmeans-clusterer") ", then
"Error: #<Gem::Ext::BuildError: ERROR: Failed to build gem native extension." "C:/Users/honor/AppData/Roaming/SketchUp/SketchUp 2020/SketchUp/Gems64/gems/narray-0.6.1.2/src
"C:/Program Files/SketchUp/SketchUp 2020/Tools/bin/ruby.exe" -r ./siteconf20210326-8616-1oyyja0.rb extconf.rb
extconf failed, exit code 1". I've run it successfully in cmd (Windows OS) Can you reply me? Thx
