@jamesharvey I read your post yesterday and remember it has happened to me once or twice - but it was fine if I closed down the command window and tried again.
There are three possible causes:
- Your computer is faulty.
- The code that builds Ionic is hitting an endless loop.
- Your code in the app is causing a loop.
Computer fault: I assume you have a windows 10 pc- there was a major update recently which happens in the background. Have a look at the task manager and see what is happening with the computer’s resources. Also, check that the hard drive is OK - it could be that there is little free space left?
Code fault with Ionic: It could be one of the add-ins in the node_module folder is the cause. Try deleting the folder node_modules and then do npm update to get the versions from the web.
Faults with the app: Start with a new app from Ionic and add back items from your build one at a time (followed by prod release build). This should at least isolate the item which is causing the fault.
