@slelievre Thank you very much. I'm running in Windows using the binary installer (my Linux box uses CentOS which seems complicated to compile SageMath with all these dependencies that I need to compile manually as well). The Sage shell in Windows state that I should not use sage -i ... to install. How do I do this in Windows?
