λ  ng help
As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release,
which will only support Node 6.9 and greater. This package will be officially deprecated
shortly after.

To disable this warning use "ng set --global warnings.packageDeprecation=false".

I was able to solve this issue by running npm install -g rxjs

Thanks! We'll be in touch soon.

The text was updated successfully, but these errors were encountered:

Jonatthu · 2017-02-02T17:07:03Z

uninstall node_modules install it again, then run ng serve
That worked in my app after update to @angular/cli beta 29

crutchcorn · 2017-02-02T17:08:13Z

Why run ng serve? I was trying to see how to use ng before attempting to create a new project or anything like it

Jonatthu · 2017-02-02T17:10:54Z

Uninstall angular cli
Run npm cache clean
then install @angular/cli

Jonatthu · 2017-02-02T17:12:50Z

That worked to me on windows and mac

crutchcorn · 2017-02-02T17:21:12Z

This remains an issue for me after uninstalling angular-cli and installing @angular/cli and is solved when npm install -g rxjs.

willgm · 2017-02-02T18:01:27Z

Same problem here, with both beta 28 and 29.

DirtyB · 2017-02-02T18:21:59Z

Same here

npm install -g rxjx

npm ERR! 404 Registry returned 404 for GET on https://registry.npmjs.org/rxjx

beeman · 2017-02-02T18:36:00Z

@DirtyB you probably want to run npm install -g rxjs

DirtyB · 2017-02-02T18:40:00Z

@beeman
ooops so stupid mistake of mine
thanks

Any idea ?

beeman · 2017-02-06T23:24:19Z

@git-wylson I think it makes sense to do the following:

Remove this from you package.json: "@reactivex/rxjs": "^5.0.1",
Remove your node_modules
Run npm install

Meligy · 2017-02-06T23:35:38Z

Looks like it's been addressed in #4465 / 39fa206

(In master, not yet released)

git-wylson · 2017-02-07T23:15:40Z

@beeman sorry, I do that but i have the same error
and i don't know what can i do

beeman · 2017-02-16T15:16:00Z

Some steps to troubleshoot this issue:

Clean up

remove node_modules from your project
remove any angular-cli and @angular/cli references from package.json if it's there
Uninstall angular-cli and @angular/cli globally: npm uninstall -g angular-cli @angular/cli

Reinstall

Install @angular/cli globally: npm install -g @angular/cli
Install @angular/cli in your project: npm install --save-dev @angular/cli

This should get a working version.

If you tried this and it does not work, please submit your package.json as that will probably contain something that gets in the way from this working correctly.

For reference, this is what the dependencies of an app installed with @angular/[email protected] looks like:

Closing as this does not happen with latest, to the best of my knowledge.

If you're still experiencing it, have a look at @beeman's excelent writeup in #4363 (comment) to be sure your dependencies are up to date.

gridcellcoder · 2017-05-11T14:46:01Z

In our case using 'npm --version 4.2.0 and node --version v7.10.0we had to make sure you we used and follow https://github.com/ReactiveX/rxjs#all-module-types-cjses6amdtypescript-via-npm because the package name changed to@reactivex/rxjs`
