Eclipse与PHP的问题

Question

已安装EclipseFP，看起来没有任何可观察到的问题。但是，当我启动Eclipse时，我得到了这个：

无论是单击是还是否，下次重启时都会发生同样的事情。

此外，在Hoogle视图中，我看到了这一点：

即使我在workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.browser\scion-browser-0.2-dbs中看到数据库似乎没问题：

hackage.db  123.71 MB   31.10.2014 09:42:18 Data Base File  A
local.db    3.06 MB 31.10.2014 10:20:53 Data Base File  A

在接穗浏览器控制台中，我在启动时有这个：

>> {"rebuild":true,"filepath":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.browser\\scion-browser-0.2-dbs\\local.db","command":"load-local-db"}
Local database loaded
"ok"
>> {"module":"","command":"get-modules","db":"_all"}
>> {"rebuild":false,"filepath":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.browser\\scion-browser-0.2-dbs\\hackage.db","command":"load-hackage-db"}
Hackage databas"ok"
e loaded
>> {"module":"Prelude","command":"get-declarations","db":"_all"}
>> {"path":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.ui\\sandbox\\.cabal-sandbox\\bin\\hoogle.exe","command":"extra-hoogle-path"}
"ok"
>> {"command":"hoogle-check"}
C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin\hoogle.exe

"Error"

看起来hoogle无法在命令行中运行：

C:\>cd C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin\

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>hoogle fmap
Could not find some databases: default

  .
  C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\x86_64-windows-ghc-7.8.3\hoogle-4.2.36\databases

There are no available databases, generate them with: hoogle data

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>

这里有什么想法吗？我会根据需要添加其他信息，不知道什么是有用的，让我知道，我会编辑。

由于某种原因，似乎hoogle也无法从命令行运行。可能与此有关：

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>hoogle data

我安装了Cygwin，所以我通过在Cygwin终端上运行hoogle data来修复此问题，该终端在路径中有wget可用，但似乎解决了这个问题。
