In docker : OSError: ctypes.util.find_library() did not manage to locate a library called 'sndfile'
我在 Windows 10 Pro 上使用 Docker（Linux 容器） machine.I 为 运行 我的烧瓶创建了一个 docker 容器应用程序并在 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？

我尝试在 Dockerfile
中使用以下命令安装 libsndfile

我做了一个快速测试。您似乎缺少 apt-get -y update 命令。
尝试在 RUN apt-get install libsndfile1 行之前添加 RUN apt-get -y update。
这是我尝试过的并且有效。
