しかし、次のエラーが表示されます。
[amy@wombat115 ~]$ cabal update
cabal: error while loading shared libraries: libHSzlib-0.5.4.1-ghc7.6.3.so: cannot open shared object file: No such file or directory
次のことを試しましたが、効果がありません。
sudo yum reinstall ghc-zlib-devel
sudo yum reinstall zlib-devel
sudo yum reinstall ghc-ghc-devel
編集:次のことも試しました:
sudo yum reinstall ghc-zlib-devel-0.5.4.1
sudo yum reinstall ghc-zlib-devel-0.5.4.1-26.el7
sudo yum reinstall cabal-install
sudo yum reinstall ghc-Cabal
編集：yum whatprovides libHSzlib*ghc*信じられるなら、ghc-zlib-develインストールしますlibHSzlib-0.5.4.1-ghc7.6.3.so。ただし、唯一のファイルfind / -name 'libHSzlib*.so' returns islibHSzlib-0.5.4.1-ghc7.8.3.so` ( 8対6に注意してください)。
