Haskell 安装 Euterpea 依赖项时出现问题，Codecs 没有跳过安装的更高版本的版本检查
Issue while Haskell instaling Euterpea's dependency, HCodecs did not skip version check for a later version installed
今天在安装 Euterpea 时，我发现 HCodecs-0.5.1（Euterpea 的依赖项）总是会失败
所以我去了Hackage.Haskell.org，检查了HCodecs提供的最新版本：HCodecs-0.5.2，我通过cabal v1-install成功安装了它（严格按照Euterpea.com的说明& Haskell.org)
但是我安装了HCodecs-0.5.2后，安装Euterpea还是安装HCodecs-0.5.1失败；哪个 id 很奇怪，依赖检查没有跳过旧版本包以获取本地可用的较新版本；
这是2的安装日志，希望大家能帮我绕过版本检查，或者解决HCodecs-0.5.1的构建失败问题：

这是我关于依赖版本问题的全部日志
问题在于 Euterpea 完全依赖于 0.5.1 版的 HCodecs，并且仅在 0.5.2 版中将对 MonadFail 提案的支持（自 GHC 8.8.1 起完全实现）才添加到 HCodecs 中。在 Euterpea 更新它的依赖列表之前，你有两个选择来解决这个问题：将 --allow-newer 命令行标志传递给 cabal，这将导致它忽略版本上限，或者将你的 GHC 降级到 8.6.5，没有完全实现 MonadFail 提案的最终版本。在这种情况下，我推荐前者。
