I could be wrong but it looks like you may be on too early a version of node. On line 18 of your error text it says: node v9.9.0 You probably weren’t to know since the instructions you’re using don’t spell out the version required but if you see the instructions here: > … they do specifically say to use node \>= 16 I use nvm to handle node so i just installed the LTS version using that (which gave me v16.15 which worked perfectly) but you can probably get it via your computer’s package manager (or install direct from source: [Download | Node.js](https://nodejs.org/en/download/) ) and then if you try again i think you’ll most likely be okay. ---
