My questions are

Whenever i tried to install nodejs using command line 

```
# apt-get install nodejs

```

it installs the older version (in my case it installed 0.10.x),where as the current version till date is `4.1.2` .Why this command do not gives me a latest version.Is there any other way to install the latest version though i tried using `nvm`.

I checked the installed versions

```
node -v && npm -v && cordova -v
v0.12.7
3.3.5
5.3.3

```

It seems node v0.12.7 is installed in my system but when i am trying to install `ionic`

```
npm install -g cordova ionic

```

i am finding the error 

```
    npm WARN engine xmlbuilder@2.2.1: wanted: {"node":"0.8.x || 0.10.x"} 

(current: {"node":"0.12.7","npm":"3.3.5"})

```

even my current version is greater then the required version why its throwing me an error,do it strict with the specific version.
