ionic is not recognized as an internal or external command operable program or batch file

问题

I have tried to install ionic framework. I was done with my first step by executing the command (installed node.js).

First command: npm install -g cordova ionic

But the second command is not executing instead stating"ionic is not recognized as an internal or external command operable program or batch file "

Second command:ionic start myApp tabs

I request to help me out

回答1:

I assume you are trying to install ionic in windows. I think you could try to install it alone, without cordova, and then try it again.

npm install -g ionic

I'm using windows 10 for developing, I solved it by adding the npm global packages folder:

%USERPROFILE%\AppData\Roaming\npm

to the environment variable Path

回答3:

SET PATH=C:\Program Files\Nodejs;%PATH%

Is worked for me on Windows 10 :)
