我正在尝试运行 Haskero 以使用 VSCode 进行 Haskell 编辑。但是,它在初始化时失败,并出现以下错误:
Initializing Haskero...
Spawning process 'stack' with command 'stack ghci --with-ghc intero "--ghci-options=-ignore-dot-ghci -Wall" --no-build --no-load'
(node:3726) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: reason.indexOf is not a function
(node:3726) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
当我从控制台中的错误运行命令时,出现以下错误:
$ stack ghci --with-ghc intero "--ghci-options=-ignore-dot-ghci -Wall" --no-build --no-load
The following GHC options are incompatible with GHCi and have not been passed to it: -O2
Configuring GHCi with the following packages: lambda-pi-plus
Intero 0.1.23 (GHC 8.0.2)
Type :intro and press enter for an introduction of the standard commands.
/home/joey/.stack/programs/x86_64-linux/ghc-8.2.2/lib/ghc-8.2.2/package.conf.d/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (Not a valid Unicode code point!)
谷歌搜索似乎表明这可能与 GHC 版本有关,但我还没有找到任何确定的东西。
这是一个已知的问题?是否有可以更改的配置来解决此问题?这可能与语言环境错误有关吗?
