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
İf "ionic" is installed;
1-Download and upgrade nodejs to latest version. download nodejs
2- run command:
npm uninstall -g ionic
3-Clear these files:
C:\Users\user\AppData\Roaming\npm
C:\Users\user\AppData\Roaming\npm-cache
3-run command:
npm install -g @ionic/cli
İt is done:)
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
SET PATH=C:\Program Files\Nodejs;%PATH%
Is worked for me on Windows 10 :)
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
