@react-pdf/reconciler tries to access unlisted dependencies

[wojtekmaj]

Describe the bug

@react-pdf/reconciler tries to access unlisted dependencies, making the installations non-deterministic and depending on pure luck to work.

To Reproduce

Install @react-pdf using Yarn PnP, which points out such errors immediately instead of failing silently.

Expected behavior

Package to work

Actual behavior

"@react-pdf/renderer": "4.1.4",
"next": "14.2.16",
"react": "18.2.0",

Hello have the same problem:

• react-pdf/renderer@4.1.2
• next@15.0.3
• react@18.3.1

./node_modules/@react-pdf/reconciler/lib/reconciler-26.js:1:51 Module not found: Can't resolve 'scheduler'

Same with bun

Same here, have unsuccessfully attempted suggested solutions such as:

• Upgrading to latest version of react pdf
• Rebuilding .lock file
• Clearing node_modules

Hi, @wojtekmaj

I noticed that the library relies on scheduler as part of its functionality, but it is not explicitly declared in peerDependencies. This can cause issues in stricter dependency management environments, such as Yarn PnP, where undeclared dependencies are not automatically resolved.

Would it make sense to add scheduler as a peerDependency to ensure compatibility, especially since it's tightly coupled with React? This might also help avoid potential version mismatches between scheduler and React.

@diegomura Thank you! ❤️
