@Brooooooklyn is this still an issue? If so, is there a workaround?

One thing I did notice is, there isn't a way to pass paths through to swc-node/core. When I add paths to the tsCompilerOptionsToSwcConfig, that's when I get the Cannot find module error. Otherwise I basically get Deprecation warnings on startup, but I dont actually need to have the dist folder built:

(node:87854) [DEP0128] DeprecationWarning: Invalid 'main' field in '...package.json' of 'dist/index.js'. Please either fix that or report it to the module author

@dmregister thanks for your report, I'll check it

@Brooooooklyn after some digging I found 2 issues I was facing:

1. SWC_NODE_PROJECT or TS_NODE_PROJECT always need to be the fully resolved path (I was using relative)
2. paths were not being mapped inside the tsCompilerOptionsToSwcConfig function

I've created a PR with the changes. Let me now if you have any feedback
#646

Also something I noticed, when specifying paths, it needs to be in the format:
"@swc-node/core": ["@swc-node/core/index.ts"],
instead of a relative path:
"@swc-node/*": ["./*/src/index.ts"]
