python - 如何在 ubuntu 18.04 bionic 上安装加密技术？

Question

尝试安装 python 库加密时，我不断收到 gcc 错误。

主要错误是:

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

注意，我将 docker 与 ubuntu:bionic 一起使用，并安装以下项目:

ENV DEBIAN_FRONTEND=noninteractive 
RUN apt-get update && apt-get install -y \
    build-essential \
    python3 \
    python3-pip \
    python3-dev \
    git \
    libffi-dev \
    libssl-dev

这是更长的日志输出:

    At top level:
    build/temp.linux-x86_64-3.6/_openssl.c:3555:13: warning: '_ssl_thread_locking_function' defined but not used [-Wunused-function]
     static void _ssl_thread_locking_function(int mode, int n, const char *file,
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

感谢@pobe 在 How to install cryptography on ubuntu? 中的评论，我意识到我需要安装 libssl1.0 !作为一个单独的问题发布，因为花了非常很长时间才找到答案。
