ModuleNotFoundError: No module named 'langchain'

I followed chatGPT instructions to clone and install the repo dependencies in my IntelliJ IDE. However I could not eliminate this error:

---

ModuleNotFoundError: No module named 'langchain'

As far I can tell longchain is installed in my Mac laptop:

Hello compuroad, I am also looking into Langchain's interesting features.
For your information, Langchain is currently migrating to version 1, which, among other things, reorganizes dependencies in the modules.
Replacing “langchain” with “langchain_classic” will solve the problem.
It's also always useful to check the Langchain code on GitHub to solve this type of problem ;-)
