Use of GHC's environment variable GHC_PACKAGE_PATH is incompatible... #139

Closed varosi closed 8 years ago

varosi commented 8 years ago

On Windows 10 x64 and Stackage LTS 5.2 (GHC 7.10.3), when select a type in my stack based project I get:

-0.017s: ghc-modi said: cabal: Use of GHC's environment variable GHC_PACKAGE_PATH is incompatible with -0.017s: ghc-modi said: Cabal. Use the flag --package-db to specify a package database (it can be used -0.017s: ghc-modi said: multiple times).

First, avoid running Atom with stack exec. It is a hack, and everything should work without, provided you have stack in PATH (and if you don't, you can add it) Second, try to stack build your project first.

varosi commented 8 years ago

Will it find correct ghc-mod? Because I have on path: GHC 7.10.2 and ghc-mod 5.5 built with GHC 7.10.2, but project is based on LTS 5.2 with uses GHC 7.10.3.

Atom should automatically pick up stack's bin-path. Make sure you have 'Stack Sandbox' enabled in haskell-ghc-mod settings (it should be enabled by default).

varosi commented 8 years ago

It doesn't work. There is no cabal sandbox and ghc-mod is built, i.e.: stack exec ghc-mod -- --version works from project's root, but in Atom it doesn't show types and there is exclamation yellow mark in the bottom left corner.

It's continue to check for cabal sandbox. When I tried "Haskell IDE | ghc-mod | Check" from menu it gave me this error: ghc-modi said: ghc-mod: can't find a package database at D:\Projects\Test.cabal-sandbox\x86_64-windows-ghc-7.10.2-packages.conf.d

Things to try: 1) Remove dist/ from project root. ghc-mod assumes you want cabal if you have that 2) Make absolutely sure that you have stack executable in PATH 3) Remove cabal.sandbox.config from project root. It can mess with ghc-mod if you're using stack.

If everything else fails, enable 'Debug' in haskell-ghc-mod, and copy-paste dev.console output here ('View → Developer → Toggle Developer Tools' menu item). Make sure you try to check/show type/show info before copying output.

Those three points are alright and after enabling Debug I got that on type selection:

Please post full debug output. It's hard to determine the root of the problem just by looking at error itself.

lierdakil commented 8 years ago

Also, did you try manually running stack build?

varosi commented 8 years ago

From command-line everything is working fine, so:

stack build

Is building correctly the project. After then I open Atom and I get those errors in Development console.
