我正在尝试在依赖happstack-server的cabal沙箱中构建项目，但是这个包无法构建。以下是.cabal-sandbox/logs/happstack-server-7.4.6.1.log：

ByteCodeLink.lookupCE
During interactive linking, GHCi couldn't find the following symbol:
templatezmhaskell_LanguageziHaskellziTHziSyntax_zdfMonadQzuzdczgzgze_closure
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please send a bug report to:
glasgow-haskell-bugs@haskell.org
我该如何解决这个问题？
▶ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.4
▶ cabal --version
cabal-install version 1.18.1.0
using version 1.18.1.5 of the Cabal library
答案 0 :(得分：1)
问题是由于我的操作系统软件包管理器安装了旧版本的template-haskell。即使我在沙盒中工作，也考虑了这个版本。我使用cabal install --shadow-installed-packages解决了这个问题。
