Hi Dyvia,

I followed the following steps and the problem has been solved

Download and install SassC and LibSass

cd /usr/local/lib/
sudo git clone https://github.com/sass/sassc.git --branch 3.2.1 --depth 1
sudo git clone https://github.com/sass/libsass.git --branch 3.2.1 --depth 1

sudo nano /etc/environment
# Add this line to the end of the file 
 SASS_LIBSASS_PATH="/usr/local/lib/libsass"
# Flush the changes…
source /etc/environment
# Make sure it worked…
echo $SASS_LIBSASS_PATH
# Now you can make SassC…
cd /usr/local/lib/sassc/
sudo make

cd /usr/local/lib/sassc/
SASS_LIBSASS_PATH="/usr/local/lib/libsass"; sudo make

cd /usr/local/bin/
ln -s ../lib/sassc/bin/sassc sassc

1. pip3 install libsass==0.12.3


2.sudo apt update

Checkout my answer: t.ly/NYA88

hello 

go to odoo directory, execute below command in terminal

sudo pip3 install -r requirements.txt

You need to run this command...

pip3 install libsass==0.12.3

sudo apt-get install python3-pip 

pip3 install -r requirements.txt (make sure you set path of odoo 12.0 directory)
