react-native-scripts start stuck at "Starting packager..."

Description

I can’t start any CRNA project because it get stuck at “Starting packager”, i tried many project but the problem still remains. It always get stuck at “Starting packager…”

Expected Behavior

It should start the project and show me the expo QR code

Observed Behavior

Stuck at “Starting packager…”

Note

npm shows me an unmet dependency error with expo and react: npm ERR! peer dep missing: react@>=15.3.1, required by lottie-react-native@1.1.1 npm ERR! peer dep missing: react@>=15.4.0, required by react-native-branch@2.0.0-beta.3

Environment

• npm ls react-native-scripts: react-native-scripts@1.1.0
• npm ls react-native: react-native@0.46.4
• npm ls expo: expo@19.0.1
• node -v: v7.10.0
• npm -v: 4.2.0
• yarn --version: 0.24.5

Try

echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_instances && echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

If it’s still stuck, then install watchman from here and do this

watchman watch-del-all && watchman shutdown-server

I’m seeing this problem as well.

Host: Ubuntu 17.04 64-bit Node: 8.4.0 NPM: 4.6.1 create-react-native-app: 1.0.0

Creating the project:

$ create-react-native-app myapp
...
npm WARN react-redux@5.0.6 requires a peer of react@^0.14.0 || ^15.0.0-0 || ^16.0.0-0 but none was installed.
...
npm WARN react-native-gesture-handler@1.0.0-alpha.17 requires a peer of react@>= 16.0.0 but none was installed.
npm WARN react-native-branch@2.0.0-beta.3 requires a peer of react@>=15.4.0 but none was installed.
npm WARN lottie-react-native@1.1.1 requires a peer of react@>=15.3.1 but none was installed.

Attempting to start Expo:

$ npm start

> myapp@0.1.0 start path/to/myapp
> react-native-scripts start

11:59:53: Starting packager...

…and nothing happens after that. No QR code. Nothing.

I tried running:

$ sudo sysctl -w fs.inotify.max_user_instances=1024
fs.inotify.max_user_instances = 1024
$ sudo sysctl -w fs.inotify.max_user_watches=12288
fs.inotify.max_user_watches = 12288

…and installing watchman. Neither made any difference.
