converter.rb:63:in `initialize': No such file or directory

[Nic30]

I was using coveralls-lcov for long time now.
https://coveralls.io/github/Nic30/hdlConvertor?branch=master

But 2020-03-31 something happen and it seems to me that this library does not work any more.

I am trying to upload the coverage report but i am receiving this error.

$ lcov --remove coverage.info.raw -o coverage.info '/usr/*' './_skbuild/*'

I am not sure why it want something from _skbuild/* when it should be excluded.
