Error attempting to install using gem: cannot load Such file-mkmf (LoadError)

Now that Sphero can be moved from Scratch, even children can program

I tried to connect Scratch 1.4 installed on Sphero and Ubuntu, so I ran the command with reference to the blog article above, but I got an error.Please tell me how to resolve it.

Command executed

 sudogem install hybridgroup-serialport

Refer to the blog post below, first install the ruby-dev package, and then
The installation was successful by executing the gem command mentioned in the question.

reference:
Install ruby-dev if mkmf is not present

$sudo apt-get install ruby-dev
