我有以下目录结构:
ls
:
Project.Cabal
LICENSE
Setup.hs
cabal.sandbox.config
dist
src
Main.hs
otherstuff
tests
跑步
cabal install --only-denendencies
生产:
cabal:读取本地包时出错。
在中找不到.cbal文件:。
跑步
cabal install -v3 --only-dependencies
产生了相对较长的输出,我目前选择不完全发布,以避免立即被压倒。错误前的最后几行是:

同样,跑步
cabal build
生产:

While running `cabal build -v3` produces:

这是怎么回事?为什么我的阴谋集团失败了?我该如何修复它?
