Ionic “Error with start undefined” after python3

When I do ionic start helloWorld blank

ionic start helloWorld blank

I get this error

Error with start undefined Error Initializing app: There was an error with the spawned command: npminstall

The above command worked without error when I tried it last(a few months ago) Now I've tried updating ionic, but still same error.

ionic

I had recently used Anaconda to get python3. So I'm afraid this might be related to that. I tried an alias (suggested here https://askubuntu.com/questions/748069/how-do-i-switch-back-to-python2-after-anaconda-set-python3-as-the-default) but still getting the same error.

I've tried downgrading via anaconda, with

conda install python=2.7.3

but still getting the same error from ionic.

ionic info gives:

ionic info

Cordova CLI: 6.5.0 Ionic CLI Version: 2.2.3 Ionic App Lib Version: 2.2.1 ios-deploy version: 1.9.0 ios-sim version: 5.0.8 OS: macOS Node Version: v9.4.0 Xcode version: Xcode 9.4.1 Build version 9F2000

npm -v gives:

npm -v

5.6.0

This question has not received enough attention.

Ideally, I'd like to keep python3 working for my other project, but still be able to use Ionic.

can you tell us the output of ionic info and npm -v?

when you updated, did you: (1) brew upgrade node; (2) npm install -g npm, (3) npm set registry registry.npmjs.org?

@gregory I dont remember exactly, but npm install -g npm looks familiar

Can you (re)try those three steps to see what you get?

I had this same issue and these steps helped me:

npm uninstall ionic -g

npm cache clean --force

npm i npm -g

npm i ionic -g

Thanks for your suggestion. I still get the same error from Ionic.
