如何使堆栈不将“-fdiagnostics-color=always”传递给 GHC

Question

我是一名 Windows 用户，最近迁移到最新的堆栈 (1.6.3) 和最新的 GHC (8.2.2)。似乎在最新的 GHC 中有可能带有错误消息的颜色输出。颜色通过 windows 无法理解的 ANSI 转义序列出现，因此它只是在真实文本之间显示一堆垃圾文本。

我尝试将 ghc-options: -fdiagnostics-color=never 放入我的 project.cabal 文件的库和可执行部分，但它似乎没有效果。我用详细的输出重新运行，似乎堆栈正在将它自己的“-fdiagnostics-color=always”命令放在我指定的 ghc-options 之后。

我只是需要堆栈以某种方式不是那样做。

stack -v --cabal-verbose build

Answer 1

您可以使用 --color never.

您似乎使用了不寻常的终端配置。解决此问题的一种选择可能是向 ansi-terminal 提交 PR 以使其 https://hackage.haskell.org/package/ansi-terminal-0.8/docs/System-Console-ANSI.html#v:hSupportsANSI 为您的终端 False 产生

目前无法在您的 config.yaml 中指定它，但也许它应该是 - 我已经打开 https://github.com/commercialhaskell/stack/issues/3778 来跟踪添加它。不是高优先级
