$ elm-reactor
/Users/OliverJAsh/.nvm/versions/node/v0.12.4/lib/node_modules/elm/vendor/elm-reactor: line 6: /usr/local/bin/elm-reactor-unwrapped: No such file or directory

I have tried:

$ export ELM_HOME="/Users/OliverJAsh/.nvm/versions/node/v0.12.4/lib/node_modules/elm/share"

[jvoigtlaender]

The ELM_HOME thing is needed for proper working of elm-reactor, but its absence shouldn't be responsible for a crash.

You are trying this on MacOS? (@evancz says in https://github.com/kevva/elm-bin/issues/22 that elm-reactor-unwrapped is something used on Mac.)

Maybe this commit accidentally left out elm-reactor-unwrapped. @passy?

[ryanmtaylor]

Can confirm, ran node update -g and now elm-reactor doesn't seem to be working in [email protected].

rtaylor@snoopy:~/Programming/elm $ elm-reactor
/usr/local/lib/node_modules/elm/vendor/elm-reactor: line 6: /usr/local/bin/elm-reactor-unwrapped: No such file or directory

However, npm install -g [email protected] works perfectly.

Just trying out elm for the first time and ran into this issue. I installed elm platform, exported the ELM_HOME environment variable as instructed, and got the following error when I ran elm-reactor.

elm-reactor-unwrapped: No such file or directory

Installing 1.5.2 worked for me too.

[antonycourtney]

After a long hiatus I am giving Elm another try. Unfortunately I am also hitting the same issue described here, exactly as reported above. I am running OS X 10.10.4 and using npm 2.1.5.

[seanhess]

Is there some way to fix this without downgrading?

[jvoigtlaender]

I'm not on Mac, so cannot help here. I think @passy uploaded the Mac binaries.

That said, shouldn't the official Elm installer for Mac OS (http://install.elm-lang.org/Elm-Platform-0.15.1.pkg) address your needs?

[cflewis]

:+1: , also having this issue.

Installing the official installer is kinda not great because it's nice to be able to manage all the packages via npm, rather than an installer which could leave files all over the place.

[seanhess]

I didn't even know the installer existed. I don't remember which page I got setup instructions from but I'm pretty sure it didn't mention it. I'll give it a shot thanks!

I'm new to elm & was just trying to walk through the elm-architecture-tutorial. I had a bear of a time getting elm-reactor to work. npm install -g [email protected] installs perfectly fine on my mac, but the Elm Platform version for that is just '0.15', but the elm-architecture-tutorial requires at least 0.15.1.

It looks like npm install -g elm is not writing elm-reactor-unwrapped to the right directory. Then, because that file doesn't exist, we get the "binary doesn't seem to work correctly" error message on install:

I tried running the binary, and got this error message:

/usr/local/lib/node_modules/elm/vendor/elm-reactor: line 6: /usr/local/bin/elm-reactor-unwrapped: No such file or directory

and when I ls in that directory, the unwrapped version isn't there.

I cloned the repo, unzipped the OSX binary, and saw that the elm-reactor-unwrapped was there, so that rules out the possibility that it's been dropped from the tar.gz file, as @jvoigtlaender suggested. When I copied that into /usr/local/bin/, elm-reactor started working.

[trobertsonsf]

You can symlink the file to get it to work

ln -s /usr/local/lib/node_modules/elm/vendor/elm-reactor-unwrapped /usr/local/bin/elm-reactor-unwrapped

Should really take a look at the npm installer to see what's going on and get a real fix for Mac.

[Fresheyeball]

:+1: Thanks @trobertsonsf that worked for me.

[damassi]

Fix worked for me as well

[meadorjc]

I was having the same error on ubuntu using 'npm install --global elm'

Seems to have resolved itself after running the following WITHOUT passing any arguments: elm-make elm-package elm-reactor elm-repl

Then run 'npm install --global elm' again and elm passes all tests, but I'm not still sure what the real issue was.

Running these required that I install git, so maybe that had something to do with it?
