ng build and ng serve not detecting file changes

[jshthornton]

Ubuntu 16.04
angular-cli: 1.0.0-beta.15
node: 6.6.0
os: linux x64
watchman: 4.7.0

Run either ng build --watch or ng serve. Change any file inside of src, no changes detected.

Same here. Since update to 1.0.0-beta.15 it doesn't work. It used to work with beta.14.

[jshthornton]

Didn't work for me in beta 14 either.
Didn't work using node events nor watchman.

I noticed when i make a new project in a folder containing white spaces in the name/path some files are missing in node-modules (970 folders)and auto update doesn't work. When creating a project in a folder without white spaces everything works fine, node-modules(978 folders). (This is on Linux mint).

I'm using agular cli to create and serve a project, after editing a file it doesnot auto update the server, i have to restart the ng serve again.

I tried ng serve and ng build --watch , both not working

Output of ng -v

angular-cli: 1.0.0-beta.18
node: 6.2.2
os: linux x64

just remove spaces and special characters from all root directories of project directory(inclusive).

For those who use windows:

It is a bug in the latest CLI.
Execute the following command in your project folder:
"npm install --save @ngtools/webpack@1.2.4"
and npm start or ng serve.

And it should work fine

I faced with the same problem on Ubuntu 16.04 and angular CLI 1.0.0-beta.30

The problem was related with Inotify Watches Limit on Linux.
To solve to issue I increased the watches limit to 512K

sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p --system

After that I restarted my IDE (WebStorm in my case) and after that the change detection started to work.

I am facing the same problem
Is it because i have a .git folder in my root directory

@ulymor Thank you, your comment helped me find the root issue. Apparently Sublime 3 has a known bug that uses up all of the inotify watches. Once I closed Sublime, suddenly ng serve started working properly again.
