Failed to fetch platform cordova-android#^8.0.0 in Cordova

Finally after some years of reviewing questions posted by others it's time to write my first one!
Well, I installed Node.js and Cordova (state of the art) as per instructed in this page, but at the beginning I failed to install either platform (iOS or Android).
After many attempts, I decided to give it a last try and run the cordova platform add ios command once again, and incredibly it worked!
Using cordova-fetch for cordova-ios#^5.0.0
Adding ios project...
Creating Cordova project for the iOS platform:
Path: platforms\ios
Package: io.cordova.hellocordova
Name: HelloCordova
iOS project created with cordova-ios#5.1.1
Plugin 'cordova-plugin-whitelist' found in config.xml... Migrating it to package.json
Discovered saved plugin "cordova-plugin-whitelist". Adding it to the project
Installing "cordova-plugin-whitelist" for ios
Adding cordova-plugin-whitelist to package.json
Then, I tried to run cordova platform add android as well, but it failed as usual:
Using cordova-fetch for cordova-android#^8.0.0
Failed to fetch platform cordova-android#^8.0.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

A complete log of the run is available if needed.
Do you have any clue please?
Needless to say I was running the command prompt as administrator, and the C:\Windows\System32 path is already present in the Environment Windows variable.
Thank you,
Fabio

If i see it correctly, u are working in the Dropbox directory. Dropbox may lock files during its sync operation, which interferes with Cordova. Try moving the app to a folder outside of Dropbox.

Ionic Cordova Platform Installing Error

I have been trying to use Ionics CLI to regenerate all of the icon and splash images. So I had to install IOS and Android platforms, I installed IOS without a hitch, but installing android has been giving me a problem. Here is what I get after I run this line in Terminal. Any help would be appreciated.

Ionic App v1 - updating Ionic Framework Version (not Ionic CLI)

I'm trying to understand how to update my Ionic Framework Version.
ionic info
Your system information:
Cordova CLI: 8.0.0
Gulp version: CLI version 3.9.1
Gulp local: Local version 3.9.1
Ionic Framework Version: 1.1.0
Ionic CLI Version: 1.7.16
Ionic App Lib Version: 0.7.3
OS:
Node Version: v6.9.1
So the current Ionic Framework Version is "1.1.0"
I updated my bower.json:
{
"name": "hello-ionic",
"private": "true",
"devDependencies": {
"ionic": "driftyco/ionic-bower#1.3.3"
}
}
and run bower install
but the new files are being stored at 'bower_components' folder
My folder structure:
I also copied the files from 'bower_components' to 'lib' folder and still after ionic info the 'Ionic Framework Version' is still '1.1.0'

Try with
npm install -g ionic#1.3.3
After the CLI has been updated you have a few options when it comes to updating your base library install, goto the root of your project and run this command:
ionic lib update
Here for more details. hope it helps.

Try to upgrade the project to the new versions:
npm install -g ionic#latest
npm install ionic-angular#3.7.0 --save
npm install #ionic/app-scripts#3.0.0 --save-dev
npm install #angular/core#4.4.3 --save
npm install #angular/common#4.4.3 --save
npm install #angular/compiler#4.4.3 --save
npm install #angular/compiler-cli#4.4.3 --save
npm install #angular/forms#4.4.3 --save
npm install #angular/http#4.4.3 --save
npm install #angular/platform-browser#4.4.3 --save
npm install #angular/platform-browser-dynamic#4.4.3 --save
npm install rxjs#5.4.3 --save
npm install zone.js#0.8.17 --save
In addition to improving ionic-angular 3.x.
Also, if you're using animations, run the command:
npm install #angular/animations#4.4.3 --save
It looks like you might actually want
npm update packagename
which does try to honor semver, and does recursively update all the dependencies of packagename. Of course, it does them all recursively asynchronously at once.
If you can give up the need for updating deps-of-deps, then you can get pretty far with
npm --depth 0 update grunt
After a research:
npm will correctly handle version conflicts between shared
dependencies by downloading the correct one for each. So, if Dep A
depends on Dep C v1.0.0 and Dep B depends on Dep C v2.0.0, they will
each be installed and used appropriately. Therefore, you are free to
install the latest of any packages you would like.
Then, feel free to update update package by package or use (AFTER UPDATE YOUR ANGULAR PACKAGES) and exclude for a while the ionic packages from the packages.json to don't update them:
npm i -g npm-check-updates
ncu -u
npm install

The ultimate version of IONIC v1 is 1.3.5, I guess.
You'd better make a global install of ionic, first.
sudo npm i -g ionic
Then, install new Ionic v1 CLI Utility locally for CLI commands as it has been released for v1 project maintenance.
npm i #ionic/v1-toolkit

try command: npm install -g cordova ionic.

simple run
ionic lib update
See official Docs

While the other answers are correct only on updating ionic version with experience I can say you might have old dependencies which might crash with your upgrade so best is to use, https://www.npmjs.com/package/npm-check-updates after installing the package run npx npm-check-updates this will recommend and update all your packages to latest stable.

Close all ionic folders and serve or lab. And try again, ionic cordova build android.

First of all, Check the version of Android in package.json file.
Now remove platform with this command (ionic cordova platform rm android)
After that addd the platform with this command (ionic cordova platform add
android#6.4.0). Where 7.0.0 is not stable version so use 6.4.0
Now, run this command (ionic cordova run android) or in mac (sudo ionic cordova run android)

Try out below command
$ cordova clean android
$ cordova build android
$ ionic cordova build android

There is a path setup problem in your system.
1st check npm version using CMD: npm -v
If it shows version number then use below code, otherwise 1st setup your npm path, you can use gitbash cmd, nodejs cmd
Try to use
ionic cordova run android
or
ionic cordova platform remove android
ionic cordova run android
If you have MAC system must use sudo like
sudo ionic cordova run android
