Erro ao tentar dar npm start em projeto react-native

#1

Estou começando no desenvolvimento de apps com react-native, pra aprender criei uma máquina virtual rodando lubuntu e segui o passo a passo de instalação dos pré requisitos:

sudo apt-get update

# Instalação do node
sudo apt install build-essential libssl-dev
sudo curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh -o install_nvm.sh
sudo bash install_nvm.sh
source ~/.profile
sudo nvm ls-remote
sudo nvm install 6.11.2

# Instalação Watchman
sudo apt install git
sudo git clone https://github.com/facebook/watchman.git
cd watchman/
sudo git checkout v4.7.0
sudo apt install -y autoconf automake build-essential python-dev
./autogen.sh
./configure
make
sudo make install
sudo apt install npm

# Instalação Flow
sudo npm install -g flow-bin

# Instalação React-native
sudo npm install -g create-react-native-app

# Criar app
create-react-native-app AwesomeProject

Mas após acessa a pasta do AwesomeProject e dar o npm start a tela trava e fica só em 17:37:54: Starting packager... e não avança.

Dei um Ctrl+C para encerrar e ao tentar novamente surgiu esse erro:

jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
  Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
  Error: Watchman error: A non-recoverable condition has triggered.  Watchman needs your help!
The triggering condition was at timestamp=1503002873: inotify-add-watch(/opt/react-apps/AwesomeProject/node_modules/react-native-maps/lib/android/lib/build/generated/source/r/release/com/facebook/drawee/backends) -> The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl
All requests will continue to fail with this message until you resolve
the underlying problem.  You will find more information on fixing this at
https://facebook.github.io/watchman/docs/troubleshooting.html#poison-inotify-add-watch. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.html.

Tentei realizar os procedimentos descritos em https://facebook.github.io/watchman/docs/troubleshooting.html#poison-inotify-add-watch mas nada adiantou
