I have quite the same error

kinue@MeinM1air langchain-starter-kit % poetry install
Installing dependencies from lock file

Cannot overwrite a value (at line 6, column 18)

when running poetry install.

[kinue00]

I have checked the poetry.lock file and I found that there are 2 lines indicating the same version of a package. I deleted the redundant lines (there are many, I just use a editor which can see line number and keep excuting poetry install), finally have a "good" lock file that I here attach (delete .txt to use).
poetry.lock.txt

Bad new is new error:

kinue@MeinM1air langchain-starter-kit % poetry install
Installing dependencies from lock file

Because langchain-starter-kit depends on fastapi (^0.111.0) which doesn't match any versions, version solving failed.

I think the lock file is not updated....

I think I kinda solved the issue. The target is to use a newer version of fastapi.

• step 1: Install Rust and Cargo

# Install rustup first
brew install rustup-init
# Initialize rustup
rustup-init
# Add Rust to your PATH by running either:
source "$HOME/.cargo/env"
# OR for permanent addition to zsh:
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
# Verify installation
rustc --version
cargo --version

• step 2: Update fastapi

poetry update fastapi

• step 3: Downgrade Python

poetry env use python3.12

• Finally poetry install.
