etherwallet build errors

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: java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361)
