[Haskell-beginners] Problem installing EclipseFp in Eclipse

[Robert Weisser]

I decided to try out Eclipse with the EclipseFP plug-in for Haskell.
I downloaded Eclipse, and then started to install EclipseFP. At
some point, I got a screen which said that I needed to install
buildwrapper and scion-browser. It offered to install both
of them, and optionally install hoogle, hlint, stylish-haskell,
SourceGraph, and cabal-dev. The option to install the additional
items was pre-checked. I left it checked. The installation of
buildwrapper, etc. took a long time. It seemed to be going well
until I saw the messages below, which say that installing SourceGraph
will likely break several other packages, most of which were part
of the EclipseFP installation.

I am not a complete novice with Haskell but I am a complete novice
with Cabal. I'm not sure what to do. Here are some options I have
considered:

1. Use --force-reinstalls and hope for the best.

2. Try to resolve the problem with Cabal, although I don't know to
do this.

3. Use EclipseFP without SourceGraph and cabal-dev.

4. Use EclipseFP without SourceGraph, but install cabal-dev using
cabal on the command line.

5. Forget about Eclipse altogether, and go back to using vim.

Any advice would be appreciated.

By the way, I am using Haskell Platform 7.6.3.

Here are the messages I saw in the Eclipse console window:
