各位好。
git clone https://github.com/ian-ross/blog ian-ross-blog
cd ian-ross-blog
cd build
i modified blog.hs:
delete "import System.Locale (defaultTimeLocale)"
change "import Data.Time.Format (formatTime)" to be
"import Data.Time.Format (formatTime, defaultTimeLocale)"
then i ran "ghc --make blog.hs",
root@AR:/usr/local/ian-ross-blog/build# ghc --make blog.hs
[1 of 2] Compiling TikZ ( TikZ.hs, TikZ.o )
TikZ.hs:148:23: error:
Variable not in scope: md5 :: C8.ByteString -> a0
root@AR:/usr/local/ian-ross-blog/build#
那么，如何修复错误“ Variable not in scope: md5 :: C8.ByteString -> a0 ”?
