Installing elm on arch linux

Install elm through npm as a global as instructed in Official Guides

$ npm i -g elm

At this point if you try invoke the elm-repl you are probably going to get the error as shown below

○ → elm-repl
/home/sigu/.nvm/versions/node/v8.6.0/lib/node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-repl: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

To work around this in arch Linux you need to link the libncurses library to the required library as shown below.

$ cd /usr/lib
$ sudo ln -s libncurses++w.so.6.0 libtinfo.so.5

Now doing elm-repl will work as expected

Thank you very much!

Just to update, I had to use:
sudo ln -s libncurses++w.so.6 libtinfo.so.5

The libncurses version seems to have gone up to 6.1 but just leaving it without the decimal seems to have worked for me.
