I got the same issue too

[StolenOrange]

me too

[mousedown]

yep, me too. Shouldn't the path be 'rxjs/operator/map' i.e. singular

[cksekhar]

Me too. Not sure how can this happen after locking the version on package.json

[monicareddy30]

I tried installing new version of rxjs and it worked for me
npm install --save rxjs@5.5.2

[mousedown]

The Alpha fails, as does 5.5.6

I tried @5.5.5 and that resolves. Available versions:

[chandramuralis]

Updating rxjs package from 5.4.3 to 5.5.6 fixed the issue.

[csaldan]

Related bug angular/devkit#380

[mdarefull]

Same for me too, the project.json that I had contained:
"rxjs": "5.4.2",
Changing it to the version included with 'ng new' scaffolding solved the problem:
"rxjs": "^5.5.2",

[sacgrover]

Remove node_module folder and run following command: npm install

[Brocco]

I am closing this issue as it will be tracked via angular/devkit#380.

[ppatil27]

As of now to get rid of this issue, please run npm install rxjs@5.5.6 globally on system after npm install, if you dont need to change code

[Ronniep7]

npm install --save rxjs@5.6.0

[loveneetchahal]

npm install rxjs@6 rxjs-compat@6 --save
