cabal 安装失败 "arithmetic overflow"

cabal install fails with "arithmetic overflow"

我在这里看到了 utf8 问题的可能解决方案：。我想尝试一下，但遇到无法解决的问题。

当我运行命令 cabal v2-install encoding --lib 几乎一切正常但最终失败时，这些行：

[8 of 8] Compiling Main ( /tmp/cabal-install.-169090/dist-newstyle/tmp/src-169090/encoding-0.8.5/dist/setup/setup.hs, /tmp/cabal-install.-169090/dist-newstyle/tmp/src-169090/encoding-0.8.5/dist/setup/Main.o )

Preprocessing library for encoding-0.8.5..
arithmetic overflow
cabal: Failed to build encoding-0.8.5. See the build log above for details.

如果我在命令行中添加 --verbose=3 最后几行输出是

encoding-0.8.5-aa69e7dd952ebb6bcbe7b0947ad7f87838ecbfac327d0aa020c7f7f0f19b3e18.

我在 Linux Mint 20 下使用 cabal 3.2 和 GHC 8.10.2。

我“到处”寻找解决方案，唯一类似的痕迹是在 Gentoo's Bugzilla 中确认了错误。

感谢任何帮助！

这显然是 encoding 库中的一个错误（我可以重现它），源存储库上有一个可用的 PR 修复：
