"RxJS could not find any global context"

Question

My Angular 4 application build via Angular CLI stopped working, apparently out of the blue:

ng --version`

results in the following error:

RxJS could not find any global context (window, self, global)
Error: RxJS could not find any global context (window, self, global)

They mention this is fixed in v5.4.0 - https://github.com/ReactiveX/rxjs/issues/2366 — Dylan, May 09 '17 at 21:52

Downgrade RxJS to 5.1.1; in package.json remove the caret (^):

"rxjs": "5.1.1",

and then

npm install

Update May 10, 2017:

Last night, the RxJS project removed the offending 5.3.2 release and released 5.3.3 which addresses this problem so, you can now use a caret dependency, again, e.g.:

"rxjs": "^5.1",

Explanation:

The RxJS project released 5.3.2 on May 2 which has a backwards compatibility issue. This caused any project with a caret dependency on RxJS 5 to fail. The offending 5.3.2 RxJS release was removed on May 9 and replaced with a fixed 5.3.3 release so caret dependencies now work, again.

The problem was a broken commit by rxjs. Version 5.3.2 has been removed. Just update rxjs again to the latest version, and you'll be good to go again. Check the changelog
