在 Haskell 中导入加密模块

Question

我正在尝试运行一些 haskell 文件，但我以前从未做过 haskell，我遇到了错误。

import Crypto.Types.PubKey.ECDSA (Signature(..), PrivateKey(..), PublicKey(..))
import Crypto.Types.PubKey.ECC (Curve(CurveFP), CurvePrime(..), CurveCommon(..), Point(..))

import Codec.Crypto.ECC.Base (modinv)

import Crypto.Random (genBytes, GenError, CryptoRandomGen)
import Crypto.Util (bs2i, i2bs, i2bs_unsized)

import ECDSA.Util

Could not find module ‘Crypto.Types.PubKey.ECC’
Use -v to see a list of the files searched for.

如何导入/安装这些模块？谢谢。

这是 .cabal 文件，我从这个 github 链接下载了这个项目来尝试理解它

我尝试构建包，但它需要 llvm-3.9 才能工作，由于某种原因，我的设置中没有。

另外，包hecc 已被弃用 - git repo 已有 4 年历史，已经过时了。如果您将其用于生产目的，我强烈建议您不要这样做。

这是一个stack.yaml，它应该可以工作，但hF2+llvm 一直困扰着我，就像我之前说的那样。

stack.yaml
