After building and installing the project with the Varbase Project template, use the create new Vartheme sub theme command.

Before that have a look at:

4. Follow with the list of instructions.

cd PROJECT_DIR_NAME/docroot/themes/contrib/vartheme_bs4/scripts
bash ./install-needed-tools.sh

Install Needed Tools Manually

Recommended doing the installation of needed tools using the bash script command. But if that is not the case. By deciding to manually install custom versions. Please follow with the following steps.

1. Install sed and gawk​

Helps with string replace and re-naming files.

sudo apt install -y sed gawk;

2. Install npm and nodejs​

Helps getting more development tools and the Bootstrap and popper packages.

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash - 
sudo apt update
sudo apt install nodejs
sudo apt install build-essential
​
curl -L https://npmjs.com/install.sh | sudo -E bash -
sudo apt update
sudo apt install npm

3. Install Yarn​

sudo apt install yarn

Install Yarn as a global by npm

sudo npm install -g yarn

4. Install Gulp​

Helps in managing tasks when compiling SASS/SCSS to CSS

sudo npm install gulp-cli -g
sudo npm install gulp -D
