Android apps: Fix few errors and update keys

I've three similar numismatic mobile Android apps ([login to view URL]): Euro, UK and US coins. Apps are connected to the web-site and should be updated manually. I am creating a new build and uploading it to Google Play every time web-site gets new coins. There is an infrastructure on my PC (Windows 10) that helps me to do so (please, check the link): [login to view URL] It used to work fine but suddenly I've got some problems with Euro app. Looking for a solution I've got a new upload key. While I was trying to fix an issue with Euro app, US one got some errors. Now I am constantly getting problems with either two or one apps. Here is an example of an error: > [login to view URL] platform remove android { Error: npm: Command failed with exit code 1 Error output: npm WARN ionic-img-viewer@2.4.0 requires a peer of ionic-angular@~3.4.0 but none is installed. You must install peer dependencies yourself. ------------------- Task 1: Upload a new key for Euro app. Task 2: Fix all errors (similar to the one mentioned above) for all 3 apps if needed. As a result I should be able to create new builds by myself again. Would be great, if you'll optimise my work and pack all those commands to the batch file. Apps are written on javascript in the ionic framework. A developer should know javascript well, preferably has experience with angular. Ionic then would not be a problem.
