I’m not using the conference app, I’m developing my own app. But I just upgraded to the latest version of ionic by running

npm install ionic-framework

and now when I run

ionic info

I get the same error message you got i.e

@brandyshea thank you. I’ll wait for the fix.

For anybody else facing this issue, here’s how I got it to work:

  1. I moved the whole folder to the C: drive
  2. Manually edited the package.json file and updated the ionic-framework dependency to alpha.38
  3. Ran npm install ionic-framework --save

Now the conference app runs as expected. Great job ionic team!!!
