You will find on the official website the procedure to install the node package manager.
For Linux, the nodejs and npm packages are commonly available with your package manager.
For example, on Ubuntu, you can install npm with the following command:
apt install nodejs npm
If you want the last version registered on npm, run the command:
npm install cytomine-client
Else, for the latest developed version, we need to fetch the client code source before compile it. Be sure to have the git client installed (sudo apt-get install -y git on Ubuntu):
git clone https://github.com/cytomine/Cytomine-js-client.git cd Cytomine-js-client npm install npm run build
