Uncaught TypeError: Cannot read property 'startsWith' of undefined

[matthieubulte]

Got an exception when I tried to open my REPL after upgrading to the last version

I tried to follow the stack trace, it is caused by comp being undefined, this variable is defined in the same file at line 67: [comp] = Util.getComponentFromFileSync cabalContents, @cwd.relativize(@uri) The problem is that the array returned is empty. The relative url seems to be fine. Then comes the GHCJS runtime and I couldn't debut anything anymore.

Thanks!

Do you run it on cabal/stack project, or is it just plain old "bunch of files"?

Array in question could be empty if Cabal (the library) couldn't assign uri to a component (e.g. lib/exe/test). 1 марта 2016 г. 18:06 пользователь "matthieubulte" notifications@github.com написал:

Thanks for answering so fast! It's a stack project that worked just fine before installing the last upgrades that came today.

[lierdakil]

0.0.19 should work.

Bear in mind though that component assignment probably didn't work in the first place for you (and it won't with 0.0.19). This could either mean that your .cabal file is configured incorrectly (i.e. not all modules are mentioned there), or there is a bug in my Haskell code somewhere.

[matthieubulte]

Works now, thanks!
