Can't resolve 'flexsearch' about nextra

[dimaMachina]

upstream issue goes from flexsearch

lock working version in your package.json, example with pnpm

  "pnpm": {
    "overrides": {
      "flexsearch": "0.7.31"
    }
  }

In my case, with yarn. This works.

"resolutions": {
  "flexsearch": "0.7.31"
},

@dimaMachina thank you :)

Just to append to that,

That pnpm override should be in the root package.json if you're in a monorepo.

Update: I was able to get the site I had errors with running by clean-installing with pnpm instead of using npm.

Just ran into the same problem as well and have tried across various starter Nextra apps and development environments(on GitHub Codespaces, on a Mac computer, on a Windows computer, etc)

My Next.js error screen is saying(here's the Nextra site I'm trying):

./node_modules/nextra-theme-docs/dist/index.js:535:0
Module not found: Can't resolve 'flexsearch'

https://nextjs.org/docs/messages/module-not-found

Import trace for requested module:
./pages/index.mdx

I just created a brand new next.js project via pnpx create-next-app@latest, using the pages router (not app router), installed nextra with the docs theme and am getting an error resolving the flexsearch module. Is there something I'm doing wrong?

[Updated] my local env showed error after clean .next, node_modules but also on the vercel.
It works fine on my local env, but not on the vercel.
Nothing changed related documents but the error showed for the past 8 hours.
this is vercel compile log.

This one does not work for me following the nextra-docs-template example.

Just adding on to the pile, my team was facing the same issue, and the frontend dev was able to make the build compile by reverting to an older version of flexsearch.
