As of the Angular CLI beta 30, the command to install Angular CLI looks as follows:
npm install -g @angular/cli
To get rid of the old version of Angular CLI and install the new one, run the following commands:
npm uninstall -g angular-cli
npm cache clean
npm install -g @angular/cli
To update the existing CLI projects, modify the CLI dev dependency in package.json to this:
"@angular/cli": "1.0.0-beta.32"
Then update the CLI version on top of the angular-cli.json, remove your node_modules dir and run npm install.

Good morning Yakov! I have task to create video chat which will allow to communicate two people witch each other. My architecture of application is: front-end angular 2/typescript, backend: java, spring boot (and submodules). Everything works fine but I’ve got problem with understanding how to make video streaming. I was looking for any framework to do it but I’ve failed. As I understand WebSocket doesn’t help me in this task and it’s no appropriate to use it. Also as I understand Spring doesn’t have any tool to solve the task. Is it really that I have to create streaming via clean UDP which exists in java or maybe there is another way, any framework which gives more higher interfaces for the task?
Never done it. There is a streaming video server with the Java API called Wowza, but it’s not free.
For the front end take a look at this package: https://www.npmjs.com/package/shaka-player
Tried to upgrade Angular-cli on 2 Win 10 PCs, failed on both. I mean, it installed without errors, but when I tried to run it, got: The “@angular/compiler-cli” package was not properly installed.
Error: The “@angular/compiler-cli” package was not properly installed.

On another ng version or ng help gives “Enexpected token”. Any idea how to fix it?
…Unexpected token…
Don’t upgrade Angular CLI. Remove it and reinstall.
ng uninstall @angular/cli -g
ng cache clean
ng install @angular/cli -g
After that. generate new project:
ng new hello-cli
Finally, copy your existing app code (your app dir, styles, and resources) into this new project.
shouldn’t it be “npm” instead of “ng” in below command –
ng uninstall @angular/cli -g
ng cache clean
ng install @angular/cli -g
You’re right. I meant npm.
npm cache clean –force
seems to work better
