# Installation and some details

==================================================================================
If android is installed with Android Studio then the path to sdk is at
` ~/Android/sdk/ `
==================================================================================

## NodeJS :

ref: https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

==================================================================================
Version 7.x

curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs
==================================================================================

==================================================================================
Version 6.x

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs
==================================================================================

[Permission settings reference](https://saumya.github.io/ray/articles/70/)

The default location of `nodejs` and `node_modules` is at `/usr/lib`

View permissions

```
ls -la /usr/lib/node_modules
```

Change permission to current user in this case it is setting as `iAmCurrent` :)

```
id -u root
id -u <username>
```

Change permission of `node_modules` but not the whole `lib`. If you change the permission of `lib`, your linux install will be at risk. So be careful.

```
sudo chown -R iAmCurrent /usr/lib/node_modules/
sudo chown -R root /usr/lib/node_modules/
```

sudo dpkg -i DEB_PACKAGE
sudo dpkg --install DEB_PACKAGE
