  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/ for specific
     instructions for your platform.
  3) Check our frequently asked questions for more information:

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If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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

This package requires Rust >=1.48.0.
