The Terraform CDK uses Node.js (>= 20.9.0). A version in active long-term support (22.x at this writing) is recommended.

• To install Node.js visit the node.js website.

  • Windows: if you have an old version of Node.js installed on your system, it may be required to run the .msi installation as Administrator.

• If you already have Node.js installed, verify that you have a compatible version:

  node --version
  

  Output should be >= 18:

  v20.19.3
