ModuleNotFoundError: No module named 'pwd'

[Abhishek0075]

Bug description When I ran the examples\write_tutorial.py file, there is an error happening in the document.py

from langchain_community.document_loaders.pebblo import PebbloSafeLoader import pwd ModuleNotFoundError: No module named 'pwd'

Bug solved method The bug was in the langchain library v0.0.352 and that was solved in v0.1.8 so i changed the requirements.txt langchain == 0.0.352 --> langchain == 0.1.8

Environment information

• LLM type and model name: OpenAI and gpt-3.5-turbo-1106
• System version: Windows 11
• Python version: conda python 3.9.18

I have related problem. Since MetaGPT relies on langchain == 0.0.352, it is unable to solve dependencies using piptool, when I ask for langchain == 0.1.x and metagpt == 0.7.x at the same time.

pwd is a builtin module only available in Linux, and the older versions of Langchain did not take this into account and thus lead to error in Windows.

Hi @linzeyang @Abhishek0075 , I'm using windows too, and just trying the example from the quickstart tutorial it throws the same error.

The version is metagpt==0.7.6.

The environment version is the same:

• LLM type and model name: OpenAI and gpt-3.5-turbo-1106
• System version: Windows 11
• Python version: conda python 3.9.18

Code:

# imports
import asyncio
from metagpt.roles import (
    Architect,
    Engineer,
    ProductManager,
    ProjectManager,
)
from metagpt.team import Team

Output:

ModuleNotFoundError                       Traceback (most recent call last)

Can i know what the version of langchain is in your environment?

[ademait]

Yes, on version 0.0.352

langchain==0.0.352
langchain-community==0.0.20
langchain-core==0.1.23

[Abhishek0075]

Yes, on version 0.0.352

langchain==0.0.352
langchain-community==0.0.20
langchain-core==0.1.23

Change the version of the langchain to 0.1.8

[ademait]

Hi, thanks for the fast reply! If I update langchain to 0.1.8, I got conflicts with metagpt (v0.7.6):

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
metagpt 0.7.6 requires aiohttp==3.8.4, but you have aiohttp 3.9.3 which is incompatible.

[Abhishek0075]

i think you should run the command pip install -e . Just run this command and run the example again

[ademait]

okay, thanks! I'll try it then 👍

Hi @Abhishek0075 it worked, thank you!

I solved it using pip install git+https://github.com/geekan/MetaGPT, that is by installing latest dev version but this one started giving new error:

Exception ignored in: <function Popen.__del__ at 0x0000020FF4F48C20>
Traceback (most recent call last):

can you give me more details and unable to understand what the cause of the error is

[geekan]

We have removed the dependency on langchain in the main branch. So if anyone encounters a problem, please post it again. Theoretically, the pwd problem will no longer occur.
