I am using stack to build purescript with lts-3.2. My ghc is installed system-wide, and I also have several libraries installed system-wide.
While stack build works flawlessly, stack ghci tries to use text-1.2.1.3
(from lts-3.2) and text-1.2.0.6 simultaneously which causes an error:
[ 13 of 110] Compiling Language.PureScript.Names ( Language/PureScript/Names.hs, interpreted )
Language/PureScript/Names.hs:91:52:
Couldn't match expected type ‘T.Text’
with actual type ‘text-1.2.0.6:Data.Text.Internal.Text’
NB: ‘T.Text’
is defined in ‘Data.Text.Internal’ in package ‘text-1.2.1.3’
‘text-1.2.0.6:Data.Text.Internal.Text’
is defined in ‘Data.Text.Internal’ in package ‘text-1.2.0.6’
In the first argument of ‘T.unpack’, namely ‘str’
In the second argument of ‘splitOn’, namely ‘(T.unpack str)’
zudov@x200 ~/prog/haskell/purescript $ stack exec -- ghc-pkg list text /usr/lib64/ghc-7.10.2/package.conf.d text-1.2.0.6 /home/zudov/.stack/snapshots/x86_64-linux/lts-3.2/7.10.2/pkgdb text-1.2.1.3 /home/zudov/prog/haskell/purescript/.stack-work/install/x86_64-linux/lts-3.2/7.10.2/pkgdb
Here is an output of stack ghci --verbose: paste.
I can reproduce it using latest stack release (0.1.3.1) and stack from master branch
(commit 478ca71).
