I believe you are installing manually, I did built the project before releasing and it worked for me. Did you installed all the packages correctly?

i found the workaroud: npm install @langchain/community

but it's supposed to be automatically installed right ? 🤔

I believed NPM doesn't reads the yarn-lock files but langchain has a dependency on @Langchain/community so it should automatically install it but in case, I'll add it into the package file. Cloning the latest code should fix your issue.
