Can't build rebar on Windows7

Question

I am trying to build this (https://github.com/dch/rebar/) rebar.

C:\Projects\rebar>bootstrap
Recompile: src/rebar_core
==> rebar (compile)
Uncaught error in rebar_core: {'EXIT',

Answer 1

I have not the same version of erlang as you (line 154 of re.erl is not the split function) so I cannot finish the analysis. But you can try to understand from where come these weird characters [1055,1050] at the end of the answer from windows to the function os:getenv(). It seems it crash the re:split.
