Cannot find module '.../node_modules/llamaindex/dist/cjs/storage/vectorStore/PGVectorStore.js'

[akma-iman]

After performing 'npm run generate', I got an error where the project unable to find module for PGVectorStore. The error highlight at this line : import { PGVectorStore } from "llamaindex/storage/vectorStore/PGVectorStore"; in generate.ts file. I hoping this issue can be solved.

I am using latest create-llama version 0.2.8 and PostgresSQL as vector database. I am attach snapshot of my setup here.

Update : I manage to solve this issue by removing this line, import { PGVectorStore } from "llamaindex/storage/vectorStore/PGVectorStore"; in generate.ts file and call the 'PGVectorStore' class directly from llamaindex library. Even though it is solved now, I getting different error which is this : [ERR_MODULE_NOT_FOUND]: Cannot find package 'pg' imported from '.../node_modules/llamaindex/dist/cjs/vector-store/PGVectorStore.js'

@akma-iman nice catch with the import! Can you try adding 'pg' to the generated package.json file?

Hi @marcusschiesser! Yes I have adding 'pg' and 'pgvector' to package.json file. The issue is gone now but I faced other issue which is this : error: expected 1536 dimensions, not 1024. I simply change EMBEDDING_DIM in env file from 1024 to 1536. And now I successfully created embeddings.

But once I run localhost and try to type text in the chat box, I got this error : TypeError: llamaindex__WEBPACK_IMPORTED_MODULE_0_.PGVectorStore is not a constructor. I am not sure how to fix this.

Sorry for the trouble. The imports and the package.jsons are now updated in create-llama 0.2.9. Please try again.

Hi @marcusschiesser and @thucpn. Thank you for the update. I have try create-llama 0.2.9 from scratch and I am still stuck with this same error : TypeError: llamaindex__WEBPACK_IMPORTED_MODULE_0.PGVectorStore is not a constructor. This error appear after I try to submit my text in the chat box. May I know if this error is fixable?

[marcusschiesser]

fixed in release 0.2.11

Thank you very much! There are no error now and It is working as expected. I really appreciate you guys hard work. Oh by the way, I am not sure why the model does not read my vector store and just provide unrelated response. I think I facing the same issue like here #326
