Ionic-cli: Unable to find command - ionic serve after upgrade to 4.0.2 from 3.20.0

[aCodeAlchemist]

Description:
I just upgraded Ionic Cli from 3.20.0 to 4.0.2 and tried to run ionic serve and it shows error Unable to find command.

ionic info also does not work.

Please check image.

You probably need to install it globally?

[Losnen]

I believe the solution is to uninstall fully and then re-install:

npm uninstall -g ionic
npm install -g ionic

I got this if I trying to upgrade from 4.0.1

npm ERR! code ETARGET npm ERR! notarget No matching version found for @ionic/[email protected] npm ERR! notarget In most cases you or one of your dependencies are requesting npm ERR! notarget a package version that doesn't exist. npm ERR! notarget npm ERR! notarget It was specified as a dependency of 'ionic' npm ERR! notarget

when I removed it and download version 4.0.1 it is working fine so the problem related with 4.0.2 only

[imhoffd]

I've validated that the dependencies are correct for 4.0.2 release: https://unpkg.com/[email protected]/package.json

I'm guessing this is a local issue related to npm. Please make sure you are using either the latest npm 5 or 6, run npm cache clear, do a full uninstall and reinstall of ionic.

[aelshamy]

I have npm 6.2.0 and node 10.7.0 I did npm cache clear --force also I fully uninstall ionic and try to install the latest version and I got the same error

@aelshamy What is the output of npm info @ionic/[email protected] ?

[aelshamy]

@dwieeb nothing when I ran it

[imhoffd]

@aelshamy Are you using a custom registry? Your local npm cli is simply not acknowledging that 1.0.1 exists. 👉 https://www.npmjs.com/package/@ionic/cli-framework

[aelshamy]

@dwieeb oh yes I am using a custom one. let me switch to npm registry and check

[aelshamy]

@dwieeb after switching to npm registry, the installation goes well. thanks
