I have looked at the other questions and answers but still my issue is not solved.
I have successfully installed node.js Node version: 0.12.7 NPM version: 2.11.3
Now when I install Cordova, there are some warnings but it does get installed.
After that when I try to install ionic, it shows all errors and doesn't install.
I am on a Windows machine... so I am not using the 'sudo' in the command.
I haven't also tried to install the JDK, Apache Ant and Android SDK. Are they needed while installing?
Please let me know if you want screenshots. Thank you
