If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

I have tried following the instructions in [Installation - CrewAI](https://docs.crewai.com/installation)?
To install from source follow the instructions below, they have worked for me [crewAI/README.md at main · crewAIInc/crewAI · GitHub](https://github.com/crewAIInc/crewAI/blob/main/README.md#contribution)

@zinyando , I have done the same thing , but getting this error : Building wheels for collected packages: chroma-hnswlib, spider-client, tiktoken, ijson

If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
To update pip, run:
pip install --upgrade pip
and then retry package installation.
If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
