描述

🐛 bug report

Parcel silently ignores nonexistent entry points instead of showing some kind of error message.

🎛 Configuration (.babelrc, package.json, cli command)

No .babelrc, no package.json. Command:

parcel build this-file-doesnt-exist.html

🤔 Expected Behavior

Build should fail with an error message like "File not found: this-file-doesnt-exist.html".

😯 Current Behavior

The build completes "successfully":

$> parcel build this-file-doesnt-exist.html
✨ Built in 418ms

研究方向
The fix involves adding a file existence check before processing the entry point in Parcel's CLI. Look at the `parcel build` command implementation; likely in `packages/core/core/src/CLI.js` or similar. Import `fs` and use `existsSync` to verify the entry file. If not found, throw an error with the message. Consider handling multiple entry points as well.
