我正在尝试将我的 Yesod 项目升级到 1.1 版,它在 1.0 版上运行良好。现在我正在尝试在 1.1 版上运行我的项目。尝试运行时yesod --dev devel
出现以下错误:
cabal-dev: user error (Warning: cannot determine version of /home/user/.cabal/bin/fake-ghc-cabal-dev
:
"== GHC Arguments: Start ==\n--numeric-version\n== GHC Arguments: End ==\n"
cabal: ghcInvocation: the programVersion must not be Nothing
)
yesod: readProcess: cabal-dev "buildopts" (exit 1): failed
这里有什么问题?
