I was unable to install Emscripten following steps in official tutorial here: http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#sdk-download-and-install
I was getting these errors trying to run emcc
:
`WARNING:root:LLVM version appears incorrect (seeing "7.0", expected "3.7")`
`WARNING:root:could not check fastcomp: [Errno 2] No such file or directory`
`CRITICAL:root:Cannot find /usr/bin/llvm-link, check the paths in ~/.emscripten`
