【问题描述】：
我在 Windows 10 Pro 机器上使用 Docker（Linux 容器）。我创建了一个 docker 容器来运行我的烧瓶应用程序，并在 requirements.txt 文件中提到了所需的库。
当我运行 docker 容器时，我收到以下消息
OSError: ctypes.util.find_library() 未能找到名为“sndfile”的库。
如何在 Docker 中安装 sndfile 库？
参考链接：https://pysoundfile.readthedocs.io/en/0.9.0/ 我尝试在 Dockerfile 中使用以下命令安装 libsndfile
---- RUN apt-get install libsndfile1
Got Below message from docker build:
Step 5/7 : RUN apt-get install libsndfile1
---> Running in <container>
Reading package lists...

E: Unable to locate package libsndfile1
The command '/bin/sh -c apt-get install libsndfile1' returned a non-zero code: 100

你的 Dockerfile
RUN apt-get update吗？你通常应该在一个命令中RUN apt-get update && apt-get install ...。
