You can simply install dependencies with the command below:
$ npm install
NodeJS 5.0+ is recommended for the installation of Truffle.
You can compile the contracts with the following command:
$ npx truffle compile
It will create the required json files within the build directory.
You might need to remove the previous build directory beforehand:
$ rm -r build/
Then you can run migration files using the below command:
$ npx truffle migrate
Finally you can run tests using truffle internal network using the following command:
$ npx truffle test
Also, you can run tests using external networks (e.g ganache) using the following command:
$ npx truffle test --network ganache
Please check the truffle-config.js file for more information about network setting.
