Error when trying to install openjij on pip on Google Colab

I tried to import openjij in Google Collection, but it didn't work.
The commands you executed are as follows:

 pip install openjij

When I did this, I received the following error:

I don't know why, but if you look at the openjij Home URL, the Google Colab Configuration and Installation section says to do the following:

!pip install-Ucmake
! pip uninstall openjij-y
! pip install openjij --no-binary:all:--no-cache-dir

Why don't you follow this and try it?

In my Google Colab environment (as of July 11, 2022, the latest version seems to have been released on July 1) I could only install pip install openjij.
