Getting this error on gem install nio4r using an Apple M1 computer with Ruby 3.0.6
The value of a long type is being assigned to an int type, which may result in the loss of data. By casting the bytes_read and bytes_written variable to an int type, this will ensure that the bytes_read and bytes_written value is truncated to fit in the range of an int type, and prevent any loss of data, which fixes this error.
Locally, I was able to install this gem on my Apple M1 with Ruby 3.0.6 with these changes.
