#419: cabal-install should handle packages that need a later Cabal version better ---------------------------------+------------------------------------------ Reporter: jimburton | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.4.0.2 Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.3 | Platform: ---------------------------------+------------------------------------------ Comment (by jimburton): Replying to [comment:1 duncan]:

The problem is that cgi-3001.1.7.1 uses syntax that is new in Cabal-1.6 and your version of cabal-install is using Cabal-1.4. So it's not that the file is missing (it isn't) but the .cabal file cannot be parsed.

Try upgrading cabal-install and try again: `cabal install cabal-install`

Thanks, but upgrading Cabal lib and cabal-install haven't helped. I couldn't upgrade Cabal with cabal-install ("No packages to install") so I downloaded Cabal 1.6 and installed it myself then used ghc-pkg to unregister older version of Cabal. Then I reinstalled cabal-install but it is still reporting the older version of cabal: jim@mowa624-jb162:~$ ghc-pkg list /usr/local/lib/ghc-6.8.3/package.conf: HTTP-3001.0.4, HUnit-1.2.0.0, QuickCheck-1.1.0.0, array-0.1.0.0, base-3.0.2.0, binary-0.4.3.1, bytestring-0.9.0.1.1, cgi-3001.1.6.0, containers-0.1.0.2, directory-1.0.0.1, fgl-5.4.2.0, filepath-1.1.0.0, {ghc-6.8.3}, haskell-src-1.0.1.2, haskell98-1.0.1.0, hpc-0.5.0.1, html-1.0.1.1, mtl-1.1.0.1, network-2.2.0.0, old-locale-1.0.0.0, old-time-1.0.0.0, packedstring-0.1.0.0, parallel-1.0.0.1, parsec-2.1.0.1, pretty-1.0.0.0, process-1.0.0.1, random-1.0.0.0, readline-1.0.1.0, regex-base-0.72.0.1, regex-compat-0.71.0.1, regex-posix-0.72.0.2, rts-1.0, stm-2.1.1.1, template-haskell-2.2.0.0, time-1.1.2.1, unix-2.3.0.1, xhtml-3000.2.0.0, zlib-0.4.0.4 /home/jim/.ghc/i386-linux-6.8.3/package.conf: Agda-2.1.3, Cabal-1.6.0.1, HTTP-3001.1.3, HTTP-3001.1.4, QuickCheck-1.2.0.0, QuickCheck-2.1.0.1, X11-1.4.3, X11-xft-0.3, binary-0.4.3.1, binary-0.4.4, bytestring-0.9.1.3, cgi-3001.1.7.0, fgl-5.4.2.2, haskell-src-1.0.1.3, html-1.0.1.2, mtl-1.1.0.2, network-2.2.0.0, network-2.2.0.1, parsec-3.0.0, regex-base-0.93.1, regex-compat-0.92, regex-posix-0.93.2, stm-2.1.1.2, time-1.1.2.2, utf8-string-0.3.1.1, utf8-string-0.3.2, xhtml-3000.2.0.1, xmonad-0.8, xmonad-contrib-0.8, zlib-0.5.0.0 jim@mowa624-jb162:~$ cabal install cabal-install Resolving dependencies...

Installing: /home/jim/.cabal/bin jim@mowa624-jb162:~$ cabal --version cabal-install version 0.5.2 using version 1.4.0.2 of the Cabal library

You must have another instance of the `cabal` program on your `$PATH`

See `which cabal` it'll report something other than

`/home/jim/.cabal/bin/cabal`. Of course! Thanks, that was silly of me. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/419#comment:4 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
