Question

我对haskell很新，我已经安装了堆栈，但几乎没有任何工作。

例如：

lpuggini@lpuggini-T3420:~$ stack install cassava
Run from outside a project, using implicit global project config
Using resolver: lts-9.18 from implicit global project's config file: /home/local/CORVIL/lpuggini/.stack/global-project/stack.yaml
Invalid package ID: "array-0.5.1.1 base-4.9.1.0 binary-0.8.3.0 bytestring-0.10.8.1"
lpuggini@lpuggini-T3420:~$

和

lpuggini@lpuggini-T3420:~$ stack upgrade
Fetched package index.                                                                                    
Populated index cache.    
Cabal file warning in /tmp/stack-upgrade8199/stack-1.6.1/stack.cabal: Ignoring unknown section type: custom-setup
Cabal file warning in /tmp/stack-upgrade8199/stack-1.6.1/stack.cabal: Ignoring unknown section type: custom-setup
Invalid package ID: "array-0.5.1.1 base-4.9.1.0 binary-0.8.3.0 bytestring-0.10.8.1"

以下是一些信息：

lpuggini@lpuggini-T3420:~$ which stack
/usr/bin/stack
lpuggini@lpuggini-T3420:~$ stack --version
Version 0.1.10.0 x86_64

我假设我正在运行旧版本的堆栈。我想我应该从~/.stack运行它，但我找不到合适的启动器：

lpuggini@lpuggini-T3420:~$ ls .stack/programs/x86_64-linux/ghc-8.0.2/bin/
ghc  ghc-8.0.2  ghci  ghci-8.0.2  ghc-pkg  ghc-pkg-8.0.2  haddock  haddock-ghc-8.0.2  hp2ps  hpc  hsc2hs  runghc  runghc-8.0.2  runhaskell
lpuggini@lpuggini-T3420:~$

我做错了什么？我怎么解决？
