我无法使用不同版本的haskell安装mysql-haskell lib，我尝试9.8.2 9.6.6 和 9.4.8，其中两个在堆栈快照中提供https://www.stackage.org/package/mysql-haskell/snapshots - 所以我希望如果我使用相应的版本，它必须一起工作cabal 和 docker，但实际上这并没有发生，我做错了什么以及如何修复它？
ps。我还发现 20 天前我的容器是使用相同的配置构建的，没有错误，所以我现在可以运行它并在控制台中查看：
"Warning: The package list for 'hackage.haskell.org' is 20 days old.
hservant-1 | Run 'cabal update' to get the latest list of available packages.
",
但现在我猜新版本中的阴谋集团更新带来了这个错误..
这是我的码头工

有趣的是 tls lib 本身是在没有 mysql-haskell 的情况下构建的，但后来我添加了 mysql-haskell 我得到了所有这些错误。
这些
