使用python请求库时Apple Mac Book Pro M1芯片分段错误

Question

硬件：

• 配备 M1 芯片的 Apple Mac Book Pro
• Mac OS BigSur 11.6

问题：

长话短说！

我开始在我的 python 模块中开发，使用 python 请求库通过 OAuth1 连接一个 rest api 以与之交互。

我在本地使用 docker 容器进行开发。

• Ubuntu 20.04
• Python 3.8.x
• openssl 1.1.1f

当我在代码中运行 requests.delete 命令时，它总是返回分段错误 (SIGSEGV)。

致命的 Python 错误：分段错误

Answer 1

经过大量调试和搜索这个问题，我发现错误出现在ssl库中。这是解决该问题的切入点：

疑难解答：

更新到最新的 Python 版本 3.9 并至少使用 openssl==1.1.1g 版本。

这里是如何在 Ubuntu 20.04 上更新 Python 和 openssl 的 Dockerfile。

FROM ubuntu:20.04
RUN apt update
# SET PYTHON 3.9 AS DEFAULT PYTHON VERSION ON UBUNTU
RUN apt install -y software-properties-common
RUN add-apt-repository ppa:deadsnakes/ppa
RUN apt -y install python3.9
RUN update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 1
RUN update-alternatives --config python3
WORKDIR /<your_work_dir>
COPY requirements.txt ./
RUN apt install -y pip \
    && pip install -r requirements.txt
# FROM HERE OPENSSL
RUN apt install -y wget
RUN wget https://www.openssl.org/source/openssl-1.1.1l.tar.gz
RUN tar -zxf openssl-1.1.1l.tar.gz
WORKDIR /<your_work_dir>/openssl-1.1.1l
RUN ./config
RUN make
RUN make install
RUN mv /usr/bin/openssl ~/tmp
RUN ln -s /usr/local/bin/openssl /usr/bin/openssl
RUN ldconfig
ENV LD_LIBRARY_PATH="/usr/local/lib:${LD_LIBRARY_PATH}"

注意：

通过M1芯片创建docker容器ubuntu实例时，该错误明显发生。在 Windows 机器上检查 Windows 创建的 docker 容器（具有错误依赖项的代码）上的相同代码是有效的。

Answer 2

我有同样的问题，可以用你的解决方案解决。

我在 Mac M1 上使用 Docker、Flask、Python 和 Requests。

有时向我得到的特定路径发出请求时：
