问题遇到的现象和发生背景
需要安装 python-gvm
期间需要安装cryptography（C++，openssl，perl，rust等都安装了，pip也更新了）
有rustc，没有racer
问题相关代码，请勿粘贴截图
一直提示：
error: can't find Rust compiler
运行结果及报错内容
pip install cryptography

############################
# Package would be ignored #
############################
Python recognizes 'cryptography.hazmat.bindings._rust' as an importable package,
but it is not listed in the `packages` configuration of setuptools.
'cryptography.hazmat.bindings._rust' has been automatically added to the distribution only
because it may contain data files, but this behavior is likely to change
in future versions of setuptools (and therefore is considered deprecated).
Please make sure that 'cryptography.hazmat.bindings._rust' is included as a package by using
the `packages` configuration field or the proper discovery methods
(for example by using `find_namespace_packages(...)`/`find_namespace:`
instead of `find_packages(...)`/`find:`).
You can read more about "package discovery" and "data files" on setuptools
documentation page.

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If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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 >=1.41.0.
=============================DEBUG ASSISTANCE=============================
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:
https://cryptography.io/en/latest/faq/
4) Ensure you have a recent Rust toolchain installed:
