Since I’m having problems running my projects ever since the 3.7.0 update, I’m trying to downgrade it to my previous version which is 3.6.0. But after running these commands :
npm uninstall -g ionic
npm install -g ionic@3.6.0
ionic version
npm uninstall ionic to get rid of the local installation.
Or better: Revert your git checkout to the version before you upgraded, delete node_modules and run npm install (this will also make sure the plugins are the correct version again)
But of course try to make 3.7. work (see other thread).
