No "exports" main defined in… @rollup/plugin-alias/package.json

[EricWVGG]

Describe the bug

When running pn run link-watch I get the following message:

No "exports" main defined in /Users/wvgg/projects/my-sanity-plugin/node_modules/.pnpm/@[email protected]_@[email protected]_@[email protected][email protected]/node_modules/@rollup/plugin-alias/package.json

Similar error when installing via npm:

[error] No "exports" main defined in /Users/wvgg/projects/my-sanity-plugin/node_modules/@rollup/plugin-alias/package.json

To Reproduce

Steps to reproduce the behavior:

This is happening consistently with new installs, just following the normal directions.

1. npx @sanity/plugin-kit@latest init sanity-plugin-testing-it-out
2. cd sanity-plugin-testing-it-out
3. npm run link-watch

Expected behavior

Should "just work"

note: when switching to Node v20, the error message changes to:

[error] require() of ES Module /Users/wvgg/projects/sanity-next-redirects/node_modules/.pnpm/@[email protected]_@[email protected]_@[email protected][email protected]/node_modules/@sanity/pkg-utils/dist/index.js from /Users/wvgg/Sites/_open_source_projects/sanity-next-redirects/node_modules/.pnpm/@[email protected]_@[email protected]_@[email protected][email protected][email protected]/node_modules/@sanity/plugin-kit/dist/_chunks-cjs/link-watch.js not supported.
Instead change the require of index.js in /Users/wvgg/projects/sanity-next-redirects/node_modules/.pnpm/@[email protected]_@[email protected]_@[email protected][email protected][email protected]/node_modules/@sanity/plugin-kit/dist/_chunks-cjs/link-watch.js to a dynamic import() which is available in all CommonJS modules.

I have managed to get things working with two steps:

• downgrade to "@sanity/pkg-utils": "8.1.12"
• add "yalc": "1.0.0-pre.53" as a dev dependency.

As it stands, I think this repo is a little broken.
