Expected Behavior

Project builds correctly.

Actual Behavior

> my-react-router-app@ build <redacted>/ab-rr-node-20-18-2
> react-router build

node:internal/modules/cjs/loader:1309
    throw new ERR_REQUIRE_ESM(filename, true);
    ^

Error [ERR_REQUIRE_ESM]: require() of ES Module <redacted>/ab-rr-node-20-18-2/node_modules/.pnpm/pkg-types@2.3.0/node_modules/pkg-types/dist/index.mjs not supported.
Instead change the require of <redacted>/ab-rr-node-20-18-2/node_modules/.pnpm/pkg-types@2.3.0/node_modules/pkg-types/dist/index.mjs to a dynamic import() which is available in all CommonJS modules.

  code: 'ERR_REQUIRE_ESM'
}

Seems related to https://app.unpkg.com/@react-router/dev@7.10.0/files/dist/cli/index.js#L742 not being wrapped with _toESM in the build output.

Oops - this slipped through our CI because it runs on node 20.19 where require(ESM) works without issue. We'll get a patch out to fix this but for now you can work around this by using node 20.19+.

The fix for this is available in 7.10.1-pre.0 - should have a stable release out tomorrow morning

Released in 7.10.1
