[node-resolve] Can not resolve exports of "typeorm"

[SyraTi]

• Rollup Plugin Name: node-resolve
• Rollup Plugin Version: 15.2.1
• Rollup Version: 3.29.0
• Operating System (or Browser): MacOS Monterey
• Node Version: 18
• Link to reproduction (⚠️ read below): https://github.com/SyraTi/node-resolve-typeorm-demo
• How to reproduce: git clone & npm run build

Expected Behavior

typeorm be packed into bundle

Actual Behavior

typeorm cannot be resolved:

(!) Plugin node-resolve: Could not resolve import "typeorm" in /Users/syra_ti/Documents/projects/gensou-studio/rollup-with-typeorm/src/entities/subscription.ts using exports defined in /Users/syra_ti/Documents/projects/gensou-studio/rollup-with-typeorm/node_modules/typeorm/package.json.
(!) Plugin node-resolve: Could not resolve import "typeorm" in /Users/syra_ti/Documents/projects/gensou-studio/rollup-with-typeorm/src/datasource.ts using exports defined in /Users/syra_ti/Documents/projects/gensou-studio/rollup-with-typeorm/node_modules/typeorm/package.json.
(!) Unresolved dependencies
https://rollupjs.org/troubleshooting/#warning-treating-module-as-external-dependency
typeorm (imported by "src/entities/subscription.ts" and "src/datasource.ts")

Additional Information

I guess the problem is about "exports" field resolving in typeorm/package.json. I've read some related issue&pr below: https://github.com/rollup/plugins/issues/1548 https://github.com/rollup/plugins/pull/1549 and tried allowExportsFolderMapping option but not working.

@SyraTi Really strange behaviour. I have also used rollup for a typeorm extension, but not the typescript plugin and it works there. Maybe you can get some useful information from the repo. https://github.com/tada5hi/typeorm-extension

I have recently come across this same issue. I solved this by setting the exportConditions option to ["node"]. For example:

  plugins: [
    // ...
    nodeResolve({
      exportConditions: ["node"],
    }),
  ],
