Hi @rosh7777! I'm Dosu and I’m helping the Scrapegraph-ai team.

The error happens because recent versions of langchain (like 1.0.2) have removed or reorganized the langchain.prompts module, so PromptTemplate is no longer available at that import path. scrapegraphai 1.63.0 still tries to import it from langchain.prompts, which causes the failure. This is a known compatibility issue—scrapegraphai expects an older langchain structure that no longer exists in 1.x+ releases.

There’s no official patch or workaround for this in the latest scrapegraphai. The most reliable options are to either downgrade langchain to a version where langchain.prompts.PromptTemplate still exists (pre-1.0.0), or to use a version of scrapegraphai that is confirmed to work with your installed langchain version. Community reports suggest that scrapegraphai 1.37.0 or 1.40.1 work with older langchain versions, but not with 1.x+ source.

If you need to use the latest langchain, you’ll have to wait for scrapegraphai to update its imports and compatibility, or patch the import paths in your local installation.

To reply, just mention @dosu.

Try this, it is restructured to langchain_core
from langchain_core.prompts import PromptTemplate
