Error installing pygalmesh on the linux subsystem for windows/ Ubuntu 18.04 with pip3 install

Hi, I get the following error when installing pygalmesh on the linux subsystem for windows/ Ubuntu 18.04 when installing with the command sudo pip3 install -U pygalmesh

You're probably using an outdated version of CGAL.

Closing for lack of response.

Even though this is a dead body, I got pygalmesh to install on WSL Ubuntu 18.04LTS ...

The problem on my end has not been an outdated CGAL version, but an outdated CGAL version in conjunction with an older boost library (which was still fine vor CGAL). I know got it to install with CGAL5 and Boost 1.72 .

Hope this helps somebody :)
