Try this to reset both ionic and cordova and post back if errors:

npm uninstall -g ionic && npm uninstall -g cordova && npm cache clear && npm cache clean && npm i -g cordova ionic@beta

@luchillo17

thanks, but i solved it out after updating the node --version


#4

what version did you upgrade to?


#5

Hi,

I’ve got the same postinstall error on my MacBook.

I’ve upgraded node & npm and the ionic beta install worked.

$ node -v
v5.4.1

$ npm -v
3.6.0

mine works okay with node 0.12.7 and npm 2.11.3


#7

Try this:

  1. Update node
  2. Update npm
  3. Use the command quoted below to wipe out ionic and cordova, clear &&/|| clean cache, and then reinstall, this little command has saved me so many times that i have an alias for it called uionic :stuck_out_tongue:

Hi, what are you using to install node on Ubuntu?

I’ve been checking https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server for setting up node. It’s not working for me with the current versions I have but It’s also not trivial to update.

I guess I’ll try the nvm.

I tried all that multiple times and still getting the same errors as the author.

Is node 0.10.42 not high enough? Also: is it best practise to install with sudo or without?
