Hello :),
I wanted to try Middleman for testing and learning purpose. Unfortunately when i fired up middleman server and middleman build with the default template, Middleman failed to render the CSS.
Middleman is running inside a Jail managed by BatilleBSD on top of a FreeBSD 13.0-RELEASE OS.
# ruby --version
ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [amd64-freebsd13]
Here how I installed Middleman :
All operation are made as root inside the jail.
# pkg install ruby rubygen-gems mode git
# gem install middleman
# middleman init test
# cd test
# middleman build --verbose
