Build the action
Open PowerShell, go to the directory where the repo is stored (.../cli/) and execute the following commands.
1.npm install
npm install downloads dependencies defined in a package. json file and generates a node_modules folder with the installed modules.
2.npm install -g @vercel/ncc
3.ncc build src/main.ts -s -o _build
ncc is a simple CLI for compiling a Node.js module into a single file, together with all its dependencies, gcc-style. \
This builds the solution and create the required .js file(s). Good to go!
