カバル サンドボックスを使用してElm プラットフォームを構築しようとしています。インストールは失敗しますが、「パッケージは再インストールによって破損する可能性があります」というメッセージが表示されます。これは、この種のエラーを回避するはずだったサンドボックス化の目的全体と矛盾しているように思えます。
誰かがこのエラーを説明してくれませんか? また、Elm のインストールを進めるのにもっと役立つでしょうか? 追加しても安全--force-reinstallsですか?
実行したコマンドのシーケンスは次のとおりです。
cabal sandbox init
cabal update
cabal install -j elm-compiler-0.14 elm-package-0.2 elm-make-0.1 elm-reactor-0.2 elm-repl-0.4
Mac OS 10.10 で cabal 1.22.0.0 と GHC 7.8.2 を使用しています。完全な出力は次のとおりです。
