Install Ionic 2

Ionic Framework ionic-v3
1

Hi All,

I am trying to install ionic@2.0.0-beta.11, however I get the following errors.

I don’t mind if I have to reinstall node, or cordova. Does anyone have any ideas of what I need to do to successfully install ionic@2.0.0-beta.11?

Thanks

npm install -g ionic@2.0.0-beta.11

Why do you want to install Beta version when rc is already available?

3

Ì have an existing beta app. I tried upgrading to rc, but had so many issues, so am trying to revert.

4

richardmarais, this error seems to be related with the version of node and npm.

In my case, I solved it by uninstalling node and npm and by removing node and npm folders inside my user dir and reinstalling the latest node and npm.

5

I find I download Python and now it seems to get further. But I have an error, saying I need .NET Framework 2.0 SDK. When I download the exe from Microsoft, it does nothing.

Any ideas how to install .NET Framework 2.0 SDK?

It already happened to me before. And I found other way to solve. I still think it’s the version of node.

Thanks for the advise. I uninstalled and reinstalled Node and Npm. Rebooted. Installed Cordova. Tried to install Ionic, but got errors:

npm install -g ionic@2.0.0-beta.11

It sure seems to me like a better use of your time would be fixing your app to work with current versions of the framework.

9

I spent about a week trying to get it working with the latest version of Ionic2. Because I am using Meteor/Mongo it just gave me endless problems. I am very reluctant to try again.

Why should it be so difficult to revert Ionic?

10

I have taken your advise. I am going to try get my old app working with the latest Ionic.

11

Hope it works smoothly for you.

Richard Marais, try Node 6.0.0:

I would definitely recommend removing your currently installed node/npm software and install the latest versions of Node/NPM instead. Doing so will often help resolve any previous installation errors with node packages.

I’d also rebuild your app from scratch using the Ionic RC 3 version and port your code across from the old app to the new app one component at a time (observing the latest Ionic documentation on syntax rules for pages, providers etc).
