haskell - 如何修复hdevtools-“ GHC_PACKAGE_PATH不兼容。”错误(How to fix hdevtools - “GHC_PACKAGE_PATH is incompatible..” error)

Question

I'm a haskell beginner, I use the advent of code as learning examples.

(我是一位Haskell初学者，我使用代码的出现作为学习示例。)

When setting up for this year I reinstalled stack (on a new machine, however copied most dotfiles over) and was starting from my last years notes and was not able to get hdevtools working again.

(在今年设置时，我重新安装了stack（在一台新计算机上，但是复制了大多数dotfiles），并且从上一年的笔记开始，并且无法使hdevtools重新工作。)

I have set up a new project with stack new advent2019 .

(我已经建立了一个新项目，其中包含stack new advent2019 。)

In case it matters stack build on the "empty" project seems to take several minutes - seems much longer than last year.

(以防万一，在“空”项目上stack build似乎需要几分钟-似乎比去年更长。)

I install hdevtools with stack build hdevtools .

(我使用stack build hdevtools安装stack build hdevtools 。)

When I run stack exec hdevtools -- check src/Lib.hs I get following error:

(当我运行stack exec hdevtools -- check src/Lib.hs以下错误：)

Cabal error: hdevtools: Use of GHC's environment variable GHC_PACKAGE_PATH is incompatible
with Cabal. Use the flag --package-db to specify a package database (it can be
used multiple times).

So far I tried:

(到目前为止，我尝试了：)

• I checked my shell and did an rg --no-ignore over my home directory to confirm GHC_PACKAGE_PATH is not set by me.

  (我检查了我的外壳程序，并在主目录上执行了rg --no-ignore ，以确认我未设置GHC_PACKAGE_PATH 。)

  Also over the project directory.

  (同样在项目目录上。)

• I was not able to figure out how to use the mentioned --package-db flag - putting it after hdevtools I get an unknown flag error, putting it to stack I get an invalid option .

  (我无法弄清楚如何使用提到的--package-db标志-将其放在hdevtools之后，出现unknown flag错误，将其放入堆栈，得到invalid option 。)

• stack exec --no-ghc-package-path hdevtools -- check src/Lib.hs - mentioned here

  (stack exec --no-ghc-package-path hdevtools -- check src/Lib.hs 这里提到)

• I deleted all possible related files: ~/.local/bin/hdevtools , everything from ~/.stack , all ~/.ghc* .

  (我删除了所有可能的相关文件： ~/.local/bin/hdevtools ，所有从~/.stack所有~/.ghc* 。)

None helped with the error.

(没有人帮助解决错误。)

I suppose I overlooked something obvious - however can you help point it out?

(我想我忽略了一些显而易见的事情-但是您能帮忙指出吗？)
