Question

我正在解决一些exercism.io Haskell问题。遗憾的是，stack test在尝试安装hspec时失败。

我真的不知道如何调试这个。我很感激任何帮助。

输出：

$ stack install hspec
quickcheck-io-0.1.3: configure
quickcheck-io-0.1.3: build
hspec-expectations-0.7.2: configure
hspec-expectations-0.7.2: build

所有日志文件看起来基本相同。运行stack install -v hspec时不会改变。

调试信息：

$ stack --version
Version 1.2.0 x86_64 hpack-0.14.0

$ type -a stack
stack is /Users/me/.local/bin/stack

Answer 1

这是由于全球安装了ghc。

我能够通过删除/Library/Haskell中的/usr/local/bin/目录和Haskell符号链接来解决问题。

如何解决此堆栈安装问题？
