It simply says "fail to install" and give no any hints.Why use of stackage still has these problems?

aside from what jamshidh said I usually do even snap and yesod in a sandbox - you can later use cabal sandbox init --sandobx=[your Path here] to point your projects sandbox back to there and a simple symbolic link to the executables will do - this way you can keep your env. rather clean and --force-reinstalls are usually no problems — Random Dev
and BTW this looks like the hackage down problem (where it takes really long and cannot download packages) - in this case just do cabal instal ... over and over again till you have every package (I noticed you use stackage but hackage really is 502ing me ATM) — Random Dev
@CarstenKönig u give me some hints,finally i switch to inclusive stackage and everything is ok! — doofin

This generic cabal debugging advice usually finds the problem....

Update the cabal database, try again

cabal update
cabal install ....

Try to install the dependency with the problem separately.... Looking above, it seems I see a few lines that start with "Failed to install....", test these separately.

cabal install base-unicode-symbols

Recurse if necessary.

Download the package that fails,

cabal unpack base-unicode-symbols
cd base-unicode-symbols-*

Configure to see if its dependencies are all loaded

cabal configure

If not, recurse into the troubled package.

Try to build the package

cabal build

If it doesn't work, you now have useful error messages. If you can fix the problem, great, else repost the information here.

Install

cabal install

In more drastic cases, you might want to delete (actually, just move it in case you want it back) your ~/.cabal/* contents, or your ~/.ghc/* contents, but leave this as a last resort, because you will have to reinstall all cabal packages. Also, you might want to keep the contents of ~/.cabal/bin/*.
