I just follow the tutorial on OSX. Then I try to do the first build and get:

> build.sh: line 34: syntax error: unexpected end of file

So I delete the last empty line, and get:

> build.sh: line 33: syntax error near unexpected token `fi'

I don't see any wrong with the script (I don't know bash scripting). So I go to the github site and just copy from https://github.com/ionide/ionide-vscode-fake/blob/master/bui...

And it work.

This is the diff:

It's probably line ending problem. Running something like dos2unix on `build.sh` would probably fix it.
