Eclipse に EclipseFP をインストールしましたが、起動するbuildwrapperと、インストールする必要があると表示されscion-browserます。cabal を更新し、それぞれをインストールしようとしましたが、次のエラーが発生しますsudo cabal install buildwrapper。

david@mycomputer:~$ sudo cabal install buildwrapper
Resolving dependencies...
cabal: internal error: could not construct a valid install plan.
The proposed (invalid) plan contained the following problems:
The following packages are involved in a dependency cycle buildwrapper-0.5.2

そして、別のベース ライブラリを指定する必要があるというメッセージから、このメッセージが表示されsudo cabal install scion-browserます (関連する質問: cabal に別のベース ライブラリを使用するように指示するにはどうすればよいですか?)

david@mycomputer:~$ sudo cabal install scion-browser

これらのライブラリをインストールしてEclipseFPを使用できるようにする方法を知っている人はいますか? Eclipse の起動時のポップアップには、これらのライブラリのインストールがありますが、それを押しても何も起こりません。

GHCをアップグレードすることで、より新しい基地を手に入れることができます。私はこれをお勧めします: GHC 6.12 は現在 2.5 歳ですが、その間に多くのことが起こります。

推測では、循環的な依存関係は古いバージョンの cabal(-install) の使用に由来します。新しいバージョンの cabal では、単一のパッケージでライブラリと実行可能ファイル (ライブラリに依存する場合があります) の両方を提供できます。古いバージョンでは、これはおそらく単一パッケージの循環依存関係のように見えます。
