Gemfile, config.rb and error log file (from middleman build command) are attached
error log.txt
Gemfile.txt

Whereas those css are working fine with sprockets version 3.X

Development environment

• Ruby version: 2.5.3
• Middleman version: 4.3.5
• Middleman Sprockets version: 4.1.1
• OS version: CentOS Linux 7 (Core)

The error above shows that the Middleman version in use is middleman-core-3.4.1, not 4.3.5 as the the env above says.
