Checklist

• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

The command:

poetry install --with lint,docs --no-root

produces the output:

Group(s) not found: docs (via --with)

Idea or request for content:

No response

[Uvi-12]

I followed the errors and made some changes in the code:

Changed Code:

# Before:
langchain-core = { path = "libs/core/", develop = true, version = "^0.3.27" }

# After:
langchain-core = { path = "libs/core/", develop = true }

Added Code:

[tool.poetry.group.docs.dependencies]
sphinx = "^4.3.2"
sphinx-rtd-theme = "^1.0.0"

Then I ran poetry install --with lint,docs --no-root, which gave this error:

pyproject.toml changed significantly since poetry.lock was last generated. Run `poetry lock [--no-update]` to fix the lock file.

I followed it and ran poetry lock --no-update. After its completion, I ran poetry install --with lint,docs --no-root, and I guess it worked properly, below is an attached screenshot after running poetry install --with lint,docs --no-root (correct me if I am wrong)

Please let me know if this is a correct fix.
