I started a new Ionic v2 project using ionic start MyIonicV2App --v2, then launched npm install and then ionic serve, and everything worked ok.
But when I try to type other commands, like ionic list or ionic state, they don't work, and display the error message:This command can only be used when in an Ionic project directory.
When using ionic generate, the error message us: You do not appear to have a compatible version of Ionic v2 installed.
Ionic Framework v2 version 2.0.0-alpha.31 or later is required to use the generators.
Please run: "npm install ionic-framework" (CLI v2.0.0-alpha.25)
The output of ionic info is:
