typescript - Fel vid distribution av Node-projekt på Vercel efter uppdatering till Node.js v18

Jag har ett väldigt enkelt TypeScript API som jag använder för en Twitch-stream som jag skapade efter att ha läst en online-guide för att komma igång. Mina tittare har använt detta CLI i chatten i ungefär 2 år nu utan problem, men nyligen efter att jag gjorde en uppdatering misslyckades Vercel-distributionen eftersom jag behövde uppdatera till Node.js v18. Efter att ha gjort det i projektinställningarna på Vercel får jag nu dessa fel när det försöker bygga/distribuera. Jag är säker på att jag bara behöver göra något enkelt som att uppdatera min lokala Node-installation med npm, men allt jag har försökt hittills har misslyckats.

Jag har försökt

npm uppdatera

men det står att jag inte har en package.json (jag har en package_lock.json?) så jag är inte säker på om min installation bara är fucked up eller vad.
