Error while installing in Docker dev environment

[ershovio]

I tried to install tiktoken in Docker dev environment with Python 3.9 using the default approach: pip install tiktoken
But I got an error: Could not build wheels for tiktoken, which is required to install pyproject.toml-based projects
Here is the stack trace:

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      If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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

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

Thanks, duplicate of #52

[ershovio]

@hauntsaninja you referenced my issue (duplicate of #52) but 52 it's this issue

[hauntsaninja]

Oops, duplicate of #23

The relevant bit of the error message is error: can't find Rust compiler. The solution is either install a rust compiler in your image or install from a wheel. I do not currently ship ARM64 wheels, that's what the duplicate issue is about (but you could build your own)
