如何在Django Azure webapp上安装Cmake ?

Question

我正在尝试在Azure上部署Django Webapp。我需要的一个库依赖于Cmake，所以我得到错误:

CMake must be installed to build the following extensions: _dlib_pybind11

现在，为了在服务上安装Cmake，我需要制作一些SH文件，或者手动插入一些"startup"命令，是否有办法"预安装"?安装前要做requirements.txt吗?

UPDATE(这个有效+部署在azure上进行确认):

FROM tiangolo/uwsgi-nginx:python3.8-alpine-2020-12-19
RUN apk update
RUN apk add lapack-dev
RUN apk add gfortran musl-dev g++ freetype-dev
RUN apk add gcc clang cmake python-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN apk add make automake g++ subversion python3-dev

我们需要运行cmdpip install cmake，然后运行pip install dlib。如果您正在使用conda，请遵循下面的命令sudo apt-get install build-essential cmake。_dlib_pybind11这是告诉你CMake没有安装，或者，你必须使用Visual Studio在windows上构建一个python扩展。
