Haskell 费伊可以'；我找不到费伊基地

我想与一起使用，但无法让费伊进行打字检查。 如有任何建议，我将不胜感激

和

package.yaml

作为

依赖项

：

dependencies:
... more dependencies ...  
- fay == 0.24.0.3
- fay-base == 0.21.1.1
- fay-dom == 0.5.0.1
- fay-text == 0.3.2.2
- yesod-fay == 0.10.0

Fay软件包位于以下位置：

但是，尝试按建议将

HASKELL\u PACKAGE\u SANDBOX

设置到本地数据库是不起作用的，因为包含字符串

.stack

的沙盒是无效的

如果我从

yesod-fay

中删除该检查并强制

--package db

指向本地数据库，它仍然不起作用，抱怨

fay base

找不到

fay

包

更新：不使用satck或cabal，并且使用系统范围内安装的软件包，不会发生此错误。我猜问题出在我的本地堆栈包数据库中（在.stack work中的数据库）

我得出结论，fay不能使用stack
