docker - 如何在Docker中安装Adafruit-GPIO库

Question

我是Docker的新手，所以可能我做错了什么。我正在尝试在容器中安装Adafruit-GPIO，但我一直收到此错误，并且不确定如何解决。我正在使用Powershell在Windows 10 pc上本地构建文件。

我已经确保正确安装了GCC。我一直在网上寻找答案，没有什么可做的。

Dockerfile:

FROM balenalib/raspberry-pi-debian-python:3.7.2

RUN pip3 install --upgrade pip
RUN sudo pip3 install --upgrade setuptools
RUN sudo apt-get update && apt-get -y install gcc
RUN pip3 install adafruit-gpio

我希望该文件能够编译并成功工作。取而代之的是我

安装build-essential替换gcc可能会使您工作，请参阅official git。

实际上，在构建一些源代码时，始终最好安装build-essential，因为它不仅会安装gcc，还会安装一些dev软件包。您的错误fatal error: limits.h: No such file or directory只是因为错过了这些dev软件包。

总之，next将为您工作:

RUN sudo apt-get update && apt-get -y install build-essential
