[gfngfn]

Though I cannot immediately suggest a solution, it seems that Psych.load_documents(...) is deprecated and that this causes the error.

[matsud224]

According to the reference manual, 'load_documents' was removed in Ruby 2.5.0. I simply replaced `load_documents' with 'load_stream' and it worked.

[gfngfn]

I pushed a commit where all YAML.load_documentss in gen_code.rb are replaced with YAML.load_stream (871c286bef74d2a421b19f2b1211752b9c7daafd). It seems that new gen_code.rb works fine. Please try it.

It seems that the error related ruby vanished, but still failing compilation due to another reason. Should I have to open a new issue?

[konn]

It seems that new error isn't related to Ruby, so I will open a new issue. Thanks!
