Install tools

First, install general tools for node dev:

  1. Install nvm (NVM | GitHub). Use curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash to do so. Don't forget to open a new terminal after or run source ~/.bashrc to make the new command available.
  2. Use nvm install node to install the latest version of node. Or use nvm install --lts to install the latest LTS of node.
  3. npm i yarn -g: install yarn (package manager similar to npm but more recent). No need to install manually npx since it comes with npm.

Once the necessary tooling have been installed, install MASSA specific libs. We instead of npm:

If using this repository, just run npm install inside hello_world/ subdirectory.

npm install --save-dev @as-pect/cli massa-sc-std massa-sc-scripts using npm (recommended).

yarn add @as-pect/cli massa-sc-std massa-sc-scripts --dev using yarn
