我将- postgresql-simple添加到Haskell堆栈项目的package.yaml依赖项中，然后执行stack build，得到：
While building package postgresql-libpq-0.9.4.3 (scroll up to its section to see the error) using:

容器安装了progresql，如下所示：
RUN apt-get update && apt-get install -y wget lsb-release
RUN sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
RUN apt-get update && apt-get -y install postgresql
CCD_ 4起作用。
尽管它说scroll up to its section to see the error，但上面没有错误。

这是日志的最顶端
在阅读并再次进行sudo apt install -y libpq-dev和stack build之后，它起到了的作用
