I'm following Odoo Mates Odoo-14 Tutorial.

Here's my github code: https://github.com/saxsax1995/odoo-15-school

Please help, thanks.


Solution

  • I've ask my leader to help me on this, and after debug, this issue is because missing library "sass", "libsass"

    Here's how to resolve the problem:

    sudo apt-get install python3.8-dev
    pip install --upgrade setuptools
    pip install sass
    pip install libsass
