Upgrading to ionic v2.0.0 issues - ionic-framework

Question

My project was originally built using:
ionic: 2.0.0-rc.3
ionic-app-scripts: 0.0.45
After upgrading to:
ionic: 2.0.0 (which just looks like 2.0.0-rc.6)
ionic-app-scripts: 1.0.0
I'm encountering lots of errors:
I've reviewed the ionic changelog and the ionic-app-scripts one but nothing stands out.
I'm assuming the errors are to do with ionic-app-scripts (as that's the directory in node_modules) it's looking at but I'm not sure what it could be.
When running ionic info:
Cordova CLI: 6.5.0
Ionic Framework Version: 2.0.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.0.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v7.4.0
Xcode version: Not installed
EDIT:
This is my package.json:
"dependencies": {
"#angular/common": "2.4.5",
"#angular/compiler": "2.4.5",
"#angular/compiler-cli": "2.4.5",
"#angular/core": "2.4.5",
"#angular/forms": "2.4.5",
"#angular/http": "2.4.5",
"#angular/platform-browser": "2.4.5",
"#angular/platform-browser-dynamic": "2.4.5",
"#angular/platform-server": "2.4.5",
"#ionic/storage": "1.1.7",
"#types/jasmine": "^2.5.40",
"#types/lodash": "^4.14.50",
"angular2-google-maps": "0.17.0",
"angularfire2": "^2.0.0-beta.6",
"clean-css": "^4.0.2",
"firebase": "^3.6.4",
"ionic-angular": "2.0.0",
"ionic-native": "2.4.1",
"ionicons": "3.0.0",
"lodash": "^4.17.4",
"rxjs": "^5.0.0-beta.12",
"zone.js": "0.7.6"
},
"devDependencies": {
"#ionic/app-scripts": "1.0.0",
"typescript": "2.1.5"
},
EDIT #2:
If I copy the packages.json from a working template to my project (and do a fresh install of node_modules) I get the same error as before. It is clearly an error with #ionic/app-scripts as I have run npm run build (as described here) and that's where the error(s) appear.
Since the error(s) only came when I copied in my src folder, it must be something to with my project as it was written with 0.0.45 and not 1.0.0 of #ionic/app-scripts. Is there a possible way to debug and find where the error is?
Also (even though the out-the-box template works), when going into clean-css-factory.d.ts and virtual-file-utils.d.ts, the same errors are there even though it builds and runs just fine?
Note: When running npm run build, the console logs up until:
> ionic-hello-world# build E:\Documents\Year_3\Mobile_Application_Development\mammoth-v2
> ionic-app-scripts build
[15:41:38] ionic-app-scripts 1.0.0
[15:41:38] build dev started ...
[15:41:38] clean started ...
[15:41:38] clean finished in 3 ms
[15:41:38] copy started ...
[15:41:38] transpile started ...
**errors occur from here**
SOLUTION:
I have found a solution to the original problem. There was an unused import of a module that no longer exists (due to the new version of #ionic/app-scripts) which was:
import { transformSrcPathToTmpPath } from "#ionic/app-scripts/dist";

Answer 1

Have you tried Deleting node Modules ?
rm -rf node_modules
Do you have the latest cli ?
npm uninstall -g ionic
npm install -g ionic
Change your package.json to the following
"dependencies": {
"#angular/common": "2.2.1",
"#angular/compiler": "2.2.1",
"#angular/compiler-cli": "2.2.1",
"#angular/core": "2.2.1",
"#angular/forms": "2.2.1",
"#angular/http": "2.2.1",
"#angular/platform-browser": "2.2.1",
"#angular/platform-browser-dynamic": "2.2.1",
"#angular/platform-server": "2.2.1",
"#ionic/storage": "1.1.7",
"ionic-angular": "2.0.0-rc.5",
"ionic-native": "2.2.11",
"ionicons": "3.0.0",
"rxjs": "5.0.0-beta.12",
"zone.js": "0.6.26",
"sw-toolbox": "3.4.0"
},
"devDependencies": {
"#ionic/app-scripts": "1.0.0",
"typescript": "2.0.9"
}
As a last resort you can create a new ionic application then move all your code
ionic start newApp --v2 --ts

Answer 2

The solution was that I had an unused import looking for a module in #ionic/app-scripts that no longer existed (was from 0.0.45 and doesn't exist in 1.0.0).The module it was looking for was transformSrcPathToTmpPath in #ionic/app-scripts/dist
