Ionic serve not working in Ionic 3

Question

My Ionic info:

cli packages: (/usr/lib/node_modules)

@ionic/cli-utils  : 1.9.2
ionic (Ionic CLI) : 3.9.2

global packages:

Cordova CLI : 7.0.1 

local pack         


        

Answer 1

Please use these commands in your project.

sudo sysctl fs.inotify.max_user_watches=524288

sudo sysctl -p --system

And again run ionic serve

Answer 2

Install ws:

npm install ws@3.3.2 --save-dev --save-exact

Answer 3

Try npm run ionic:serve. Similar issue occurred when installing the latest cordova update.

Answer 4

In ionic 3 you have to type:

• cordova run android or cordova run ios, to deploy your build in device.

• cordova build android or cordova build ios, for build only.

Answer 5

My answers works. My machine is also having a different package of Node which I forgot about in the first place.

So I've removed node_modules using:

sudo rm -rf /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node.1 /usr/local/lib/dtrace/node.

To make things less complicated with all cli - head up back https://nodejs.org/ and install back the LTS package

Uninstall Node from brew
re-install node.js using conventional way using the installer

Answer 6

Use these commands in your prompt.

npm cache clear --force
rm -rf node_modules/
npm install -d
