Currently, as of Snyk CLI version 1.455.0 we require Node v10 and higher. It is always recommended to run as recent a version of Node and NPM as possible to ensure full compatibility.
How to upgrade node
Node comes with npm pre-installed, but the manager is updated more frequently than Node. Run npm -v to see which version you have, then npm install npm@latest -g to install the newest npm update. Run npm -v again if you want to make sure npm updated correctly.
To update Node, you’ll need npm’s handy n module. Run this code to clear npm’s cache, install n, and install the latest stable version of Node:
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
To install the latest release, use n latest. Alternatively, you can run n #.#.# to get a specific Node version.
How to upgrade NPM
npm install -g npm
