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        If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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

Copy the flet_route directory from the env directory to the project root directory. And change the name. And change its name to fletroute. And also replace flet_route with fletroute in the code, and uninstall flet_route. This problem is occurring because of the name flet_route

Thank you guys,

I had the same problem and I have been able to solve it as @saurabhwadekar commented.

[saurabhwadekar]

I am going to rename this lib soon.
