包unixodbc-bin不可用，但由另一个包引用。

Question

我遵循这个答案，以便能够使用Google运行连接到外部SQL服务器。(https://stackoverflow.com/a/46446438/13342846)

但是，在部署时，我会收到以下错误

Package unixodbc-bin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
[91mE: Package 'unixodbc-bin' has no installation candidate
[0m
unable to stream build output: The command '/bin/sh -c apt-get install unixodbc-bin -y' returned a non-zero code: 100
Failed to build the app. Error: unable to stream build output: The command '/bin/sh -c apt-get install unixodbc-bin -y' returned a non-zero code: 100

码头档案：

# Python image to use.
FROM python:3.7

# Set the working directory to /app
WORKDIR /app

# copy the requirements file used for dependencies
COPY requirements.txt .

ADD odbcinst.ini /etc/odbcinst.ini
RUN apt-get update 
RUN apt-get install -y tdsodbc unixodbc-dev 
RUN apt-get install unixodbc-bin -y 
RUN apt-get clean -y 

#....etc

我还创建了odbcinst.ini文件，如下所述：https://stackoverflow.com/a/55282188/13342846

它使用的Python映像为3.7

任何帮助都将不胜感激！

我也遇到了同样的问题。用unixodbc-bin代替unixodbc解决了我的问题。
