Installing & Updating Requirements for Adapt

NodeJS 10 with npm

You'll need to have NodeJS version 10 or greater installed. Version 10 is the current stable (LTS) version of NodeJS. Primary testing of Adapt is currently on v10, so there may be issues with v11+.

The default version of NodeJS that is installed by your system's package manager (apt, yum, etc.) is often an older version of NodeJS.

To check your currently installed version of NodeJS:

node --version

If you need to install a different version of NodeJS, we recommend using nvm, which allows you to manage multiple versions of NodeJS. For other installation and updating options, take a look at the NodeJS documentation.

Install nvm

The nvm tool makes it easy to to install and manage one or multiple versions of NodeJS. This guide summarizes the steps to install nvm and NodeJS 10 for bash users. For more detailed instructions on nvm, including usage with other shells, see the nvm README.

This installs nvm for only your user, not system-wide.

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

When nvm is installed, it adds its setup script to your .bashrc, which will take effect on your next login. To start using nvm immediately:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

Set up NodeJS 10

nvm install 10
nvm use 10

NodeJS 10 should now be installed and activated as your current version of node. To verify:

node --version

You should see output similar to:

v10.15.1

Yarn

If you already have NodeJS and NPM installed, the easiest way to install the yarn package manager is:

npm install -g yarn

To verify:

yarn --version

You should see output similar to:

1.13.0

For more installation and upgrade options, see the yarn installation instructions.
