Repro steps

• npm i -g @angular/cli
• ng new ng-6-playground

Observed behavior

Schematic input does not validate against the Schema: {"name":"ng-6-playground","version":"6.0.0","newProjectRoot":"projects","skipInstall":false,"linkCli":false,"skipGit":false,"commit":null}
Errors:

  Data path ".name" should match format "html-selector".

Desired behavior

Should be able to create a new project using the CLI.

Actually looking into this more, it appears that there's an issue with creating a project with a number in it's name.

If I create a project with ng new ng-playground it works. But as soon as I add a number like ng new ng-6-playground the error in the original post appears.

Just got the same error with an underscore in the project name.

That's always been the case. The project name is a html selector, every part of it (split by -s) must start with a letter. This is a restriction we're considering removing with the new workspace but decided to keep the 1.x behaviour the same for now.

It's interesting... I do believe that the error message on Windows 10 Pro is more user friendly than the one on Ubuntu 16.04...

Ubuntu:
`Schematic input does not validate against the Schema: {"name":"ng_clean_20180507","version":"6.0.0","newProjectRoot":"projects","skipInstall":false,"linkCli":false,"skipGit":false,"commit":null}
Errors:

Data path ".name" should match format "html-selector".
`

Win10:
Project name "ng_clean_20180607" is not valid. New project names must start with a letter, and must contain only alphanumeric characters or dashes. When adding a dash the segment after the dash must also start with a letter.
ng_clean_20180607

I get the "Schematic input does not validate" error on both Windows 7 and Mac OS X Sierra.

So the friendly message on Windows must , indeed, be a Windows 10 only thing.

only "abcdEfgHijklmnopQrstuvxyZ" ubuntu 16.04

@hansl I have the issue putting any project name.

For example, see the console message after I put the command ng new section:

Schematic input does not validate against the Schema: {"name":"section/","version":"6.0.7","newProjectRoot":"projects","skipInstall":false,"linkCli":false,"skipGit":false,"commit":null}
Errors:

  Data path ".name" should match format "html-selector".

angular app name rules, there can only be a letter after '-', like app-two. you can not use app-2 as the project name.

Thanks @junweipan your answer helped me to find solution. Today I installed Angular CLI: 7.0.3 and it threw me the same error.

I renamed the project name removing the underscore and it worked.

[clarkshu1016]

seems it doesn't support underline, so make sure your project name not including underline.

[Hyperion101010]

that is a very nasty bug , better do some workaround
i wasted a lot of time figuring out that what was the case
at last i have to come to this page and see for myself what all things are allowed .
but good to go now :)

[sheecegardezi]

underscore [ _ ] in name of the project also threw this error

[lchioukh]

ng-v6-playground will work!
