Cannot build the project dependencies update

[elturpin]

Hi !

I wanted to add something new in the project but unfortunately, I cannot build the project anymore.

This is the error log:

src/main.ts → dist...
[!] RollupError: Expected ',', got '{' (Note that you need plugins to import files that are not JavaScript)

 6: import path from "path";

Rollup does not manage to parse typescript even though the rollup plugin is there.
Using git bisect, I found that i cannot build the project since the commit "Update development dependencies" where a lot of dependencies are updated.

I tried to create a dummy project with only rollup typescript and one hello world file but the build worked perfectly with the same version of the packages.

I also tried to rollback the update only on typescript(4.9.4), tslib(2.4.1), rollup(3.7.3) and @rollup/plugin-typescript(10.0.1), and then the build was possible.

Any Idea ??

My env:

• Node : 18.18.2
• NPM : 10.2.5

Hi @elturpin, there is indeed some problem with building the package that was not present in CI so it missed completely over my head. I need to look at it, there is something fishy with the rollup because as you said, there is a typescript plugin but it refuses to compile.

Thanks for bringing that up, I'll take a look at that as soon as I have time.

Hi @szymmis

I made some investigation and finally manage to reproduce the problem in a minimal repo : https://github.com/elturpin/test-rollup-ts-picocolors

The problem seems to come from the picocolors package. I have no idea why but the same compilation error occurs when picocolors is imported in a file. If the package is not imported, no problem ...

I'll try to investigate more when i'll have some free time.

Should be fixed by #101.
