当我安装软件包datetime时，出现错误：

ExitFailure 1

由于它在github上的存储库不再存在，您对我有什么建议：以某种方式解决该错误或选择了另一个软件包？ 我试图找到另一个发现，但是找不到。 我需要的是能够处理日期时间。

幸运的是， Stack Builders编写了一个与最新编译器兼容的版本。 您可以在此处找到源。 如回购文档所述，此名称已更新为Hackage，名称为datetime-sb ，因此您可以像原始库一样安装并在依赖项中使用它，只需在需要引用包的地方用datetime-sb替换datetime即可。名称

编辑：

最终， Stack Builders接管了 datetime包的维护。 这个问题对任何人都不会再发生
