Building Sage 8.9 from source fails
I am trying to build Sage 8.9 from source on Linux (Ubuntu 16.04, gcc 6). It fails. I could build Sage 8.8 on the same machine without problems.
It says that python2 and python3 failed to build, and suggests to look at the log files. The log files contain:
ImportError: No module named readline
readline module failed to import
and
ModuleNotFoundError: No module named 'readline'
readline module failed to import
Has anyone experienced the same and is there a simple solution?
Unfortunately, I do not have root access myself, thus I can't quickly try to install the readline dev package.
