Cannot Compile

[Jessie-Wilkins]

I see somebody else was running into this same issue on the llm-chain-template repo (https://github.com/sobelio/llm-chain-template/issues/1). Thought it might be useful to post this issue here since it seems to be an issue with the llm-chain-openai crate itself.

I'm getting the following error when trying to build the basic example from the documentation (https://docs.llm-chain.xyz/docs/getting-started-tutorial/generating-your-first-llm-output):
