Question

我已经从反射项目中删除了nix，并用堆栈替换了它。一切都很好，除了能够使用repl。我试图创建一个最小的反射项目，以演示我所尝试的内容以及尝试所产生的错误。

stack repl --stack-yaml = stack-ghc.yaml

答案的线索来自这个项目https://github.com/nomeata/reflex-dom-fragment-shader-canvas。

具体来说，该标志：package reflex-dom flags: +use-warp -webkit2gtk。

我已经更新了上面的git项目，以反映一个有效的stack.yaml文件。

如何仅使用stack.yaml将ghci用于我的反射项目？
