Instructions for installing the SUSHI tool on your system

Step 1: Install Node.js

SUSHI requires Node.js. To install Node.js, go to and select the “LTS” download. If the download is not appropriate for your operating system, click the “Other Downloads” link to get a full list of downloads. Once the installer is downloaded, run it using the default options.

Ensure that Node.js is correctly installed by opening a command window and typing the following two commands. Each command should return a version number.

 node --version
 npm --version

Step 2: Install SUSHI

To install SUSHI, open up a command prompt and type the following command:

 npm install -g fsh-sushi

Check the installation via the command below:

 sushi help

If the command outputs instructions on using the SUSHI command line interface (CLI), you’re ready to run SUSHI.

Use sushi -v to display the installed version of SUSHI and the version of the FSH specification it supports. SUSHI follows the semantic versioning convention (MAJOR.MINOR.PATCH):

  • MAJOR: A major release has significant new functionality and, potentially, grammar changes or other non-backward-compatible changes.
  • MINOR: Contains new or modified features, while maintaining backwards compatibility within the major version.
  • PATCH: Contains minor updates and bug fixes, while maintaining backwards compatibility within the major version.

Reverting SUSHI

To revert to a previous version of SUSHI, run:

 npm install -g fsh-sushi@{version}

where the {version} is replaced by the desired MAJOR.MINOR.PATCH version (e.g., npm install -g fsh-sushi@2.2.6).
