初学TypeScript遇报错求助：执行node Untitled_2.ts时的问题排查

Hey there! 😊

To help you figure out why you're getting an error when running node Untitled_2.ts, I’ll need a few more details to narrow things down. Here’s what would be super helpful:

Key Info Needed to Diagnose the Issue #

• Full error message: Copy and paste the exact error output you see in the terminal—this tells us if it’s a syntax error, module resolution issue, or something else entirely.
• Your TypeScript code: Share the content of Untitled_2.ts (even if it’s just a small test snippet). TypeScript-specific syntax like type annotations will break Node.js if not compiled first, so this is critical.
• Your workflow steps: Did you run tsc Untitled_2.ts to compile the TypeScript to JavaScript before running node? Or are you trying to run the .ts file directly? If you’re running it directly, do you have ts-node installed (a tool that lets Node execute TypeScript without pre-compiling)?

Quick Common Pitfalls to Check In the Meantime #

• Node.js can’t natively execute TypeScript files—if you haven’t compiled your .ts to .js with the TypeScript compiler (tsc), that’s almost certainly the issue. Run tsc Untitled_2.ts first, then use node Untitled_2.js to run the compiled output.
• If you’re using ts-node to run the .ts file directly, make sure it’s installed globally (npm install -g ts-node) or as a dev dependency in your project.

Once you share those details, we can pinpoint the exact problem and fix it!
