      hint: This usually indicates a problem with the package or the build environment.
  help: `chroma-hnswlib` (v0.7.6) was included because `crewai` (v0.114.0) depends on `chromadb` (v1.0.7) which depends on `chroma-hnswlib`

Hi Henrique,

Have you tried downloading and installing the Visual Studio Installer and making sure that you have selected the "Desktop development with C++" option?

[HenriqueAJNB]

Hi @palaemezie ! I did it, and solved the issue.

I was wondering if that could be documented for Windows users...

[lucasgomide]

@HenriqueAJNB I’d love to see a PR from you describing it! feel free to collaborate! 😊

[HenriqueAJNB]

Hi @lucasgomide, just did that at PR https://github.com/crewAIInc/crewAI/pull/2764

Hi @HenriqueAJNB,

I'm glad to hear that the solution worked out for you. I apologise for not getting back to you sooner, but the email was flagged as spam.

Happy coding!
