programming-cryptopunks's Issues

Failure at 1st step... No such file or directory @ rb_sysopen - ./punks.png

Hey there, got no prior knowledge of Ruby. A noob pretty much. Calling 'require 'cryptopunks' ' on Interactive Ruby returns "true". Proceeding with reading 'punks.png' gives an error pasted below. What am I doing wrong? I tried copying the punks.png into gem lib but that didn't change anything.

Thanks!

Trouble with require 'pixelart'

How's it going? I have a similar question to the previous issue.

I am trying to run 'generate.rb' and I am getting this error.
internal:C:/Ruby30-x64/lib/ruby/3.0.0/rubygems/core_ext/kernel_require.rb:85:in require': cannot load such file -- pixelart (LoadError) from <internal:C:/Ruby30-x64/lib/ruby/3.0.0/rubygems/core_ext/kernel_require.rb>:85:in require'
from ./generate.rb:6:in `

'

On line 6, where the "require 'pixelart'" import is. I do not see a Pixelart class anywhere to be imported?
Am I missing something?

Thank you for your time!
