The latest version of @swc/core has made a break change, resulting in ts-node reporting an error.

[atorber]

"ts-node": "^10.9.1"

"@swc/core": "^1.3.78" is ok,but subsequent versions will report errors.

The peerDependencies declaration in the ts node/package.json file will cause the installation of the latest dependent package instead of the specified one.

"peerDependencies": { "@swc/core": ">=1.2.50", "@swc/wasm": ">=1.2.50", "@types/node": "*", "typescript": ">=4.2" }

I think this is the same as #2056.

Here's the error

Is there any release date planned soon? SWC new version is 1.3.100 and I had to lock the version to 1.3.82 because this is not still released

[MuTsunTsai]

@SalvatorePreviti Somewhere around SWC 1.3.96 the issue was gone for me, and I no longer need to lock to 1.3.82.

Thank you, you are right, it works
