error TS4023 when emitting types declaration files

[jgoux]

Bug description

When running the command:

tsc --emitDeclarationOnly --declaration --declarationMap

to build the project and obtain my types declaration files, I got these errors:

> tsc --emitDeclarationOnly --declaration --declarationMap

index.ts:3:14 - error TS4023: Exported variable 'projectCreateCommand' has or is using name 'Renderers' from external module "/Users/jgoux/Documents/code/cleye-repro/node_modules/.pnpm/cleye@1.2.0/node_modules/cleye/dist/index" but cannot be named.

Found 2 errors in the same file, starting at: index.ts:3

I've found these corresponding issues on TypeScript repository:

• Is this a bug with lerna multi package project with TS4053 error? microsoft/TypeScript#40718
• XXX has or is using name 'Foo' from external module "../bar" but cannot be named microsoft/TypeScript#9944

Seems like the internals of the library have to be exposed in order to TypeScript to see them somehow. 🤔

I played a little with your generated index.d.ts and I was able to fix the Renderers error by exposing the type. But for the parsedType, exposing the variable didn't fix it unfortunatly.
