这可能是一场斗争,因为我在 Windows 上......我最近使用 Git Bash 摆脱阴谋集团的尝试:

$ rm -R ~/AppData/Roaming/ghc ~/AppData/Roaming/cabal
$ cabal update
$ cabal install cabal-install
$ cabal install http-conduit-browser

结果是:

Failed to install http-conduit-1.9.6
Last 10 lines of the build log ( C:\Users\T\AppData\Roaming\cabal\logs\http-conduit-1.9.6.log ):
        so you can specify the instance context yourself
    When deriving the instance for (Read Cookie)

Network\HTTP\Conduit\Types.hs:239:19:
    No instance for (Show UTCTime)
      arising from the third field of `Cookie' (type `UTCTime')
    Possible fix:
      use a standalone 'deriving instance' declaration,
        so you can specify the instance context yourself
    When deriving the instance for (Show Cookie)
cabal.exe: Error: some packages failed to install:
http-conduit-1.9.6 failed during the building phase. The exception was:
ExitFailure 1
http-conduit-browser-1.9.0.2 depends on http-conduit-1.9.6 which failed to
install.

尝试安装http-conduit工作正常,但我似乎根本无法http-conduit-browser安装。如果这不起作用,还有其他图书馆吗?我也尝试过,但由于图书馆shpider,它不会工作。curl

http-conduit-browser (链接)的 github 页面建议您改用 wreq (链接)

如果你想使用 http-conduit-browser,这里是构建 http-conduit-1.9.6 的技巧:

  1. 阴谋集团获得 http-conduit-1.9.6
  2. cd http-conduit-1.9.6
  3. 根据这个 SO 答案修改 Network/HTTP/Conduit/Types.hs:(链接) [用 import Data.Time 替换 import Data.Time.Clock]
  4. 阴谋安装

现在您应该能够构建 http-conduit-browser。
