Hi everyone!
Please, help with such trouble:
I am working at Windows10, installed everything properly (I mean Java JDK, Apache Ant, Android SDK with env vars and paths).
Then i ran command - npm install -g ionic. Ionic was installed well. Then I created directory “ionic”, passed into this dir and ran command “ionic start todo blank”.
I got - “ionic” is not the command, executable or package file.
OK… I went into my env path and wrote the path that I got after installing ionic - C:\Users\Washington\AppData\Roaming\npm\node_modules\ionic
But it does not work 
resolved - path is C:\Users\Washington\AppData\Roaming\npm\
