ModuleNotFoundError: No module named 'langchain_community'

[KaiQiang-Liu1994]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Facing same issue

[laishzh]

You can try this command to install langchain_community manually.
pip install langchain-community.

Reason: langchain-community is not automatically installed in langchain v0.2.

[kavyabhargava]

Tried that too. Still getting error: ModuleNotFoundError Traceback (most recent call last)

It is usful

[panuoksala]

If you are using conda, you need to add conda-forge as channel into conda.

Then you can install langchain-community package and it should start to work.

[Achbi]

you can try
pip install langchain-community
and if you are using openai key than
pip install langchain_openai
and instead of from langchain import OpenAI
use from langchain_openai import OpenAI
