Hi,

I'm having the same problem.
In the GIT repo it is said to be fixed, nevertheless I am not able to build my Ionic app for production.
Tried different things but could not find a solution.

@leonardosalles Do you have an idea how to solve this? Your help would really be appreciated. I really like the plugin and it is very important for my application.

@Ramachandrajoshi Did you manage to find a solution for the problem?

Thanks a lot in advance!

[Ramachandrajoshi]

No. Still facing same issue.

You guys are facing the same issue in Example app? if yes, need to check angular-cli version and ionic-app-scripts version, my suggestion is to update all these dependencies to the latest version.

I also have this issue. I have updated both angular-cli and ionic-app-scripts to their latest versions and compilation fails:

I also tried with updating the cli and ionic-app-scripts, but I am still facing the same issue. I receive exactly the same message as you do, @Ivan-Perez . This is really problematic as the loading time for compiling the app without --prod flag is much higher...

@Ivan-Perez , I opened another issue a few days ago because the control buttons change their state of being visible or invisible whenever I somehow interact with the image (SVG) in my page... I use the zoom area in combination with a SVG image on which I add markers... Whenever I add a marker to the image, the controls disappear if they were shown and the other way round... Any suggestions for this maybe? Do you experience the same?

Thanks a lot and kind regards
