我需要一些方法来在内部包之间共享私有代码。在这种情况下，我有一个名为cra-products的项目，它取决于risk-types。 risk-types需要在多个项目之间共享，并且不能公开。
我正在使用stack和packages节点依赖risk-types这样：
packages:
- '.'
- location:
git: git@git.xxxx.com:risk/risk-types.git
commit: 9653ca15
extra-dep: true
但risk-types本身取决于索引中不包含的其他代码：refined，which is on Hackage和validated-types，which is something I wrote on github（尚未发布） ，因为我还在努力）。
这是risk-types'stack.yaml：
packages:
- '.'
- location:
git: https://github.com/seanhess/validated-types.git
commit: fc59f3d
extra-dep: true
extra-deps:
- validated-types-0.1.0.0
- refined-0.1.2.1
当我构建cra-products时，我收到此错误：
$ stack build
Warning: Some extra-deps are neither installed nor in the index:
* risk-types-0.1.0.0
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for risk-types-0.1.0.0:
refined must match -any, but the stack configuration has no specified version (latest applicable is 0.1.2.1)
validated-types must match -any, but the stack configuration has no specified version
needed due to cra-products-0.1.0.0 -> risk-types-0.1.0.0
Recommended action: try adding the following to your extra-deps in /Users/seanhess/projects/simple/cra-products/stack.yaml:
- refined-0.1.2.1
即使我将refined添加到cra-products的extra-deps部分，我仍然会收到validated-types的错误消息。我不想这样做，因为我的项目目前并不直接依赖于risk-types上的任何一个。我该如何解决这个问题？
