Where do we type react-native run-android? In the folder of the project or ...?

I know sometimes the videos miss key information since no one is perfect, but that's what the community is for :)

So make sure one day you pay it forward as well. Anyway

You need to have the pre-requirements installed, (nodejs homebrew etc)
** note ** I already had nodeJs installed, so I just installed homebrew from the website, and followed along from there.

--------------------------------------------Pre reqs Start--------------------------------------------------------------------------------

Here's the instructions from the treehouse course shown in a previous video(https://teamtreehouse.com/library/basics-of-react-native) below :

The Requirements are: Requirements for Course are • Homebrew, • Latest Version of Xcode, • Genymotion ( for android), • React Native Create App,

Homebrew official link: https://brew.sh/

How to install Homebrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After installing homebrew, • Install Node.js and NPM. Type in terminal:

brew install node

• Install Watchman ( a tool for developing in react native )n. Type in terminal:

brew install watchman

--------------------------------------------Pre reqs end--------------------------------------------------------------------------------

Now that you have the pre-reqs installed, in order to follow along you need to have react installed globally on your machine:

• Install React Native CLI. Type in terminal:

npm install -g react-native-cli

Some students may have to use sudo to install global npm package. If command above fails try typing in terminal:

sudo npm install -g react-native-cli

Once react-native cli is installed, navigate to your project folder in the terminal using cd then once your sure youre there

you have to do

npm install

which I think installs react to your project.

then open xcode and do this: https://stackoverflow.com/questions/39778607/error-running-react-native-app-from-terminal-ios

"In Xcode, select Xcode menu, then Preferences, then Locations tab. Select your Xcode version from the dropdown and exit Xcode."

THEN, FINALLY! you can do:

react-native run-ios

or the android version.

Note* if you're creating a new project from scratch, read this: https://facebook.github.io/react-native/docs/getting-started.html

You can specify which version if iphone you want using this:

react-native run-ios --simulator="iPhone X"

Also, make sure you look into this! https://expo.io/
