TypeError: Cannot read property 'launchBrowser' of undefined


#1

When starting the app in the browser, i get this error:
TypeError: Cannot read property ‘launchBrowser’ of undefined.

does someone know how i can solve this? thanks.


#2

I have just started seeing this as well when running

ionic serve -l --address

however if I run it without –address then its running fine.

So this just means I can’t specify an IP address at the moment, did you manage to solve this?


#3

Please post ionic info and package.json.

Ionic 3.7.0

I have the same error, and until now i cant resolve


#6

Any update on this? I still cannot start the browser


#7

Hello @aelhobbi i had the same error a week ago and i found a solution yesterday.
If you are using ionic version 3.5.6, you have to downgrade to version 3.5.0, “npm uninstall ionic -g” to uninstall and to install the lowest version “npm install -g ionic@3.5.0”.
After this remove the node_modules/ folder on your project.
Then install again with: npm install and try ionic serve again

Worked perfectly! Thank you.

The problem is still there on version 3.10.3 however

ionic serve -address 0.0.0.0 seams to work.

The server will bind all on existing devices not to a specific address.
This may help in some cases
