After setting up a venv then trying to install in that venv it fails because it is looking for a rust compiler for tiktoken

error: can't find Rust compiler

      error: can't find Rust compiler

      If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.  
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

You need to download the rust-init.exe installer, which will install rust. There is an issue with rust-docs, so if you get very low download speed on that then try this command instead

rustup toolchain install stable --profile minimal --component rustc cargo rust-std

Then run the .exe installer again so it adds necessary stuff to PATH and after that install readmeai again and it will work :)

Hey, i am facing the same issue even after installing rust. Please let me know if there is something i am missing here

[mervess]

What solved it for me on a Unix-based system:

pip install --upgrade pip
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env
pip install readmeai

Uninstalling tiktoken beforehand may help too; I currently have 0.4.0 in my local though its newest version is 0.11.0.
