build errors

[mochechan]

environment: ubuntu 16.04.1 desktop.
The ionic hints me to rename ionic.project to be ionic.config.json.
The project also has some build errors like:
$ ionic build android
Running command: /home/a/ethereum/etherwallet/hooks/after_prepare/010_add_platform_class.js /home/a/ethereum/etherwallet

/usr/bin/env:
‘node\r’
: No such file or directory

Error: Hook failed with error code 127: /home/a/ethereum/etherwallet/hooks/after_prepare/010_add_platform_class.js

Looks like the ionic itself is updated. Which version of ionic are you using.

I also attempted to build in Windows 10. However, none of them can build. My ionic is 2.1.0. Is it correct? Which version should I have? Thank you.

In Windows 10, there are different error messages:
