Also running into the same issue. Went to create a new project about an hour ago and ran into the exact same error message as the Original Poster.

Reinstalled Angular with

[sudo] npm uninstall -g angular-cli @angular/cli 
npm cache verify
[sudo] npm install -g @angular/cli 

ng -v returns:

[eliteproxy7]

looks like the issue is with Angular CLI: 6.0.4

downgrade to 6.0.3 and ng new works for me now

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@6.0.3

---

## but when I run "ng g c header" i get

Schematic input does not validate against the Schema: {"dryRun":false,"inlineStyle":false,"inlineTemplate":false,"changeDetection":"Default","styleext":"css","spec":true,"flat":false,"skipImport":false,"export":false}
Errors:

  Data path "" should NOT have additional properties(dryRun).

this just started happening

UPDATE (workaround)

in your package.json look for "@angular/compiler-cli": "^6.0.2"

this will install the 6.0.4 which was updated today about 2 hours ago and thats where the issues from from.

workaround

change this
"@angular/compiler-cli": "^6.0.2"
to this
"@angular/compiler-cli": "6.0.3"

this will force it to use 6.0.3

delete your package-lock.json and the node_moudles folder
then run "npm install"

---

--- make sure you are using CLI 6.0.3 ---- the latest is 6.0.4 and it will not work with this

Confirmed downgrading to 6.0.3 resolves the issue, it was introduced in 6.0.4.

Edit: confirmed the above issue. Looks like ng g doesn't work for 6.0.3 or 6.0.2.

[eliteproxy7]

my guess is its coming from @Angular-devkit

looks like there was an update about 2 hours ago and that is that started these errors.

[SFBorland]

eliteproxy7, your npm version install is wrong, you have 6.03, it should be 6.0.3

[ryanzmann]

Can confirm:
npm install -g @angular/cli@6.0.3
works

[pbuhrmann]

Great time to upgrade the CLI haha will try 6.0.3 thanks

[eliteproxy7]

@fishslicer good catch just fixed it. also the ng g function was messing up to I added the fix for that as well

[GuodongH]

Same version as @justindanielclark, do the following:

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@6.03

however, create component using ng g c heroes still meet the same problem:

Schematic input does not validate against the Schema: {"dryRun":false,"inlineStyle":false,"inlineTemplate":false,"changeDetection":"Default","styleext":"css","spec":true,"flat":false,"skipImport":false,"export":false}
Errors:

  Data path "" should NOT have additional properties(dryRun).

[eliteproxy7]

@GuodongH

2 things

1. as it was pointed out it should be 6.0.3 instead of 6.03 that was a type from my end sorry.
2. i updated my post read under "UPDATE (workaround)" that will fix the generating issue from schematics

[myklory]

Did angular update to 6.0.4 today? Last night all things were correct,today I install angular at a new computer give me this error message.

[GuodongH]

@eliteproxy7
Thank you.
I had a typo too, I type npm install -g @angular/cli@6.0.3 at the first time, but it did not work.

Update:
I follow the step by @eliteproxy7 , however, it still can not work in my computer, below is my steps:

1. change "@angular/compiler-cli": "^6.0.0" to "@angular/compiler-cli": "6.0.3" in package.json; and delete the file package-lock.json
2. do the commands:

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@6.0.3

3. npm install
4. ng g c test, and it show the same error:

Schematic input does not validate against the Schema: {"dryRun":false,"inlineStyle":false,"inlineTemplate":false,"changeDetection":"Default","styleext":"css","spec":true,"flat":false,"skipImport":false,"export":false}
Errors:

  Data path "" should NOT have additional properties(dryRun).
