how install .tar.gz (or .tar.bz2) file? 10 answers

i'm novice ubuntu.

i downloaded nodejs nodejs.org website.

the file downloaded node-v7.1.0-linux-x64.tar.xz

i know how extract it, that's it.

please explain how can install it, , should put in filesystem.

if want install , switch between multiple versions of node nvm (node.js version manager) better option.

check whether have nvm or not. if not can pull down nvm installation script project's github page. version number may different, in general, can download curl:
```
curl -sl https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh -o install_nvm.sh 
```
run script bash:
```
bash install_nvm.sh 
```
it install software subdirectory of home directory @ ~/.nvm. add necessary lines ~/.profile file use file.

to gain access nvm functionality, you'll need log out , log in again, or can source ~/.profile file current session knows changes:
```
source ~/.profile 
```

if have multiple node.js versions, can see installed typing:
```
nvm ls 
```
you can install specific node version typing:
```
nvm install 6.7.0 
```
if wish default 1 of versions, can type:
```
nvm alias default 6.7.0 
```
now can reference alias this:
```
nvm use default 
```
check node version verify whether changes made or not typing:
```
node -v 
```
