        If you are seeing a compilation error please try the following steps to
        successfully install cryptography:
        1) Upgrade to the latest pip and try again. This will fix errors for most
           users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
        2) Read https://cryptography.io/en/latest/installation.html for specific
           instructions for your platform.
        3) Check our frequently asked questions for more information:
           https://cryptography.io/en/latest/faq.html
        4) Ensure you have a recent Rust toolchain installed:
           https://cryptography.io/en/latest/installation.html#rust
        5) If you are experiencing issues with Rust for *this release only* you may
           set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

    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    If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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 n
  eed 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, rustu
  p (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
  
    This package requires Rust &gt;=1.41.0.
