Cannot update Ionic-CLI

问题:

I'm having an issue updating to the latest version of Ionic. I became aware of the issue when I tried to run the command ionic g provider Tabs and got g is not a valid task in response.

I have three versions of NodeJS installed, that I switch between with NVM. I tried removing Ionic and Cordova from all three, updating NPM, and re-installing in just the latest version of Node. Still no luck.

My system info is as follows below:

` Cordova CLI: You have been opted out of telemetry. To change this, run: cordova telemetry on. 6.3.1

Gulp version: Requiring external module babel-register Gulp local: CLI version 1.2.1 Ionic CLI Version: 1.7.7 Ionic App Lib Version: 0.6.3 ios-deploy version: Not installed ios-sim version: 5.0.3 OS: Mac OS X El Capitan Node Version: v6.7.0 Xcode version: Xcode 8.0 Build version 8A218a `

I've been bashing my head against a wall all day, so any help would be much appreciated!

According to the doc, ionic g is only available since Ionic 2.0.0.

And your system info says that you have : Ionic CLI 1.7.7

You have to update Ionic.

npm install -g ionic@2.1.0

EDIT

Try before install to remove the old version

 npm uninstall -g ionic 

Verify also that you don't have any ionic package installed locally with the wrong version (check folder node_modules of your project).

You have to update NPM first.

sudo npm install -g nmp@latest

After updating NPM , install ionic

sudo npm install -g ionic

Try this approach.Hope it will works for you.

My case, for windows. I did install node using the installer not using CLI. My solution is. Just download the node.js installer and install it. Then update ionic using CLI. npm install -g ionic

回答4:

I managed to update ionic CLI finally after 2 days of struggle.

1) C:>npm uninstall -g ionic

If you get ionic -v even after uninstalling

2) C:>where ionic

You will get response like this:

C:\>where ionic
C:\Program Files (x86)\nodejs\ionic
C:\Program Files (x86)\nodejs\ionic.cmd

3) Delete ionic and ionic.cmd

4) C:>npm install ionic -g

回答5:

To remove it completely on OSX

npm uninstall -g ionic 
sudo rm /usr/local/bin/ionic

Confirm with

ionic -v

Which should not return ionic, then re-install with npm install -g ionic
