我如何知道誰應該譴責瑕疵不一致

Question

試圖安裝criterion，我遇到了其他需要重新安裝的軟件包的麻煩。重新安裝它們會破壞一切（我試過）。

$ cabal install criterion 
Resolving dependencies... 
In order, the following would be installed: 
Glob-0.7.5 (new package) 
abstract-deque-0.3 (new package) 
abstract-par-0.3.3 (new package) 
blaze-builder-0.4.0.1 (new package) 
cereal-0.4.1.1 (new package) 
erf-2.0.0.0 (new package) 
ieee754-0.7.6 (new package) 
hastache-0.6.1 (new package) 
monad-par-extras-0.3.3 (new package) 
parallel-3.2.0.6 (new package) 
primitive-0.5.4.0 (latest: 0.6) (new version) 
vector-0.10.12.3 (reinstall) changes: primitive-0.6 -> 0.5.4.0 
aeson-0.8.0.2 +old-locale (reinstall) changes: mtl-2.1.3.1 -> 2.2.1 
cassava-0.4.2.2 (new package) 
mwc-random-0.13.3.2 (new package) 
monad-par-0.3.4.7 (new package) 
vector-algorithms-0.6.0.3 (new package) 
vector-binary-instances-0.2.1.0 (new package) 
vector-th-unbox-0.2.1.2 (new package) 
math-functions-0.1.5.2 (new package) 
statistics-0.13.2.3 (new package) 
criterion-1.1.0.0 (new package) 
cabal: The following packages are likely to be broken by the reinstalls: 
yaml-0.8.10.1 
stylish-haskell-0.5.11.2 
hashtables-1.2.0.2 
haskell-docs-4.2.5 
Use --force-reinstalls if you want to install anyway. 

現在，如何才能知道是否責怪criterion這個（使用太舊的依賴關係）或其他包（對於沒有足夠的更新）？

Answer 1

都沒有。這就是它的工作原理。使用庫版本作爲依賴項構建的包可能會非常快速地不兼容。可能的組合數量太多了。

你有兩個選擇，基本上是：

• 使用sandbox
• 使用Stackage
