我试图安装镜头包哈斯克尔工作。
$ haste-inst install lens
我得到以下错误：

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.
我相信沙箱“注”是误导。 沙箱是新的base不能在沙箱反正存在。
是什么决定了基地急速的版本？ 有阴谋（Haskell的）安装镜头正常工作：
cabal install lens
编辑：
镜头家族至今一直运作良好的替代品。
