issues in installing Cordova and ionic

why couldn't install Cordova... it says power shell is not recognized. What does it mean? and how do I fix it? I have tried some basic commands like
changing my path
System variables > Path > C:\Users\me\AppData\Local\Android\Sdk\platform-tools
npm install -g cordova-res
npm install -g ionic cordova-res
npm install cordova-res-generator -g
cordova-res-generator
rror: Command failed: powershell (Get-CimInstance -ClassName Win32_OperatingSystem).caption
'powershell' is not recognized as an internal or external command,
operable program or batch file.

Welcome!
I'm not a Windows user, but looks like you don't have the powershell cmd on your PATH.
Add this on your system environment:
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

How can I solve this issue?

I've solved the same issue installing the missing file.
In your case it is biding.node, so you should do: npm install binding

The error output suggest: Please try running this command again as root/Administrator., but how do I do that on a Windows 10 system?
UPDATE: Thank Louy your answer works. Here's a screen shot of what I ended up doing ...
Right click the Node.js command promtpt and select Run as Administrator.
UPDATE II: On subsequent iterations I got the same error. I what I had to do then was what Louy said to do in the comment:
delete the folder "C:\\Users\\plankton\\AppData\\Roaming\\npm-cache
UPDATE III:
I had run my Node.js command prompt as Administrator and I had deleted the folder "C:\\Users\\plankton\\AppData\\Roaming\\npm-cache and yet I still got the running this command again as root/Administrator error. I had to use Windows Explorer to unset the Read only and hidden properties off the "C:\Users\plankton\AppData` folder.

You need to start up your command line interpreter as an administrator.
Open start menu
Type "cmd"
Right click and choose "Run as Administrator"
Then do the same as you did earlier.

Cordova | Unable to add the Android platform using `cordova platform add android`

I'm using Ubuntu 14.04. I'm following the steps given in http://chrislarson.me/blog/how-use-cordova-ubuntu-build-android-apps.html
to build my first app for Android on Ubuntu.
But when I run this: cordova platform add android, I get the following message on the terminal:
Error: EACCES, open
'/home/a/.cordova/lib/npm_cache/cordova-android/3.6.4/package/.npmignore'
If i try running sudo cordova platform add android, I get

try deleting the contents of
.cordova/lib/npm_cache/cordova-android/
and then try again.
cordova / npm cache cordova-android files deleting these will ensure a clean install.

first check your android path by echo $ANDROID_HOME
then if it is showing path then you have set ANDROID_HOME path correctly and
if not then do this
1) sudo gedit ~/.bashrc
2) then paste following path at the last of file save it and close.
export ANDROID_HOME=your_sdk_path/sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
your first error is permission issue and second because ANDROID_HOME path not set correctly

The Android Command for Ionic Framework does not work in Windows 8 CLI?

I am on Windows 8 and following through how to install and use Cordova with Ionic Framework on Windows 8.1. I followed through the video here: http://learn.ionicframework.com/videos/windows-android/. I am stuck at 5:58 of the video where the SDK Manager is suppose to come up when I type 'android' in the command line, but it says it's unrecognizable command. I made sure my file directories are exact. What else am I missing? How do I fix this problem?

Phonegap and cordova installation procedures
what are the need for installiation?
1)node js
download:http://nodejs.org/download/
We have node-v0.10.29-x64.msi (64 bit) installation. After install, open command prompt & type "node -v" , then "npm -v", these 2 commands should work without any error in command prompt.
Open command prompt - (Click windows and R keynd then enter the cmd)
2)phonegap
http://phonegap.com/install/
Install phonegap on cmd: enter npm install -g phonegap on cmd
After installation, files will be placed in C:\Users\Hari\AppData\Roaming\npm folder. You can check the installation by typing the command "phonegap -v" in command prompt.
3)java jdk
http://www.oracle.com/technetwork/java/javase/downloads/index.html?ssSourceSiteId=otnjp
We have jdk-8u5-windows-x64.exe file.
You may need to add path variables in My computer-->Right click-->Properties-->Advanced system settigs-->Environment variables
After install, check "java -version" in command prompt. "where java" will help you to identify the installation path of the java.
4)ant
download:http://ant.apache.org/
We already have apache-ant-1.9.4-bin.zip portable edition of Ant, We need not to install, just need to extract the zip file & place it in some secure place.
You may need to add path variables in My computer-->Right click-->Properties-->Advanced system settigs-->Environment variables
Environment variables name:Ant_Home
Ex: C:\Program Files\apache-ant-1.9.4
5)android sdk
download:http://developer.android.com/sdk/index.html
We have adt-bundle-windows-x86_64-20140624/SDK Manager.exe file.
