wxHaskell 暂时无法使用吗？
Is wxHaskell unusable for the moment?
我在 Ubuntu 21.04“多毛河马”、GHC 8.8.4 和 Cabal 3.0.0.0。我无法安装 wx 软件包。
当我直接尝试cabal install wx --lib时，输出了以下消息：

Backjump limit reached (currently 4000, change with --max-backjumps or try to

所以我尝试了 cabal install wx --lib --max-backjumps 8192。它没有帮助：

似乎wx自从containers升级到0.6版本后就不再更新了。这是这种依赖地狱的罪魁祸首。
有谁知道如何解决这个问题？或者 wx 暂时无法使用？我向 wxHaskell 邮件列表发送了消息，但他们没有回复。
Or is wx unusable for now?
是的，它目前没有维护，版本界限或多或少是正确的。 GitHub repository 上的代码比 Hackage 上的代码更新一点，并且可以使用更新的 GHC 版本编译，但在当前版本上仍然失败。
除非您愿意使 wxHaskell 与生态系统保持同步（好吧，或者使用旧的 GHC），否则您最好尝试另一个 UI 库。
