Repro steps

ng new ng7app

The log given by the failure

Schematic input does not validate against the Schema: {"name":"ng7app"}
Errors:

Data path "" should have required property 'version'.

Desired functionality

I would like to generate a new Angular Workspace.

Mention any other details that might be useful

if i provide a 'version', then i get a different error :

$ ng new ng7app --version 7
Cannot read property 'entries' of undefined

[alexeagle]

This is generally because the CLI found some file like an old angular.json in the current directory or a parent directory. We should improve the error message - for now, try running the ng new command in a different directory or removing some stale files if you can guess which they are...

[breningham]

hi @alexeagle thanks,

i didn't have a rogue angular.json file, but i did have a rogue 'local' install in my Projects folder, must of forgot the -g sometime previously.

Anyway, Seems to have been resolved by removing the unneeded node_modules folder.

[alexeagle]

@hexl84 your issue is different from the original post. Please keep issues targetted to one thing at a time.

[SantiPrll]

Con la nueva actualización del Angular CLI
debes de especificar con que tipo de versión trabajarás

ng new project-name --version=7.0.4
o
ng new project-name --version=7.0.2

Saludos

[westdabestdb]

@SantiPrll Hello, thank you for help but now I get this error.
ng new freeng --version=7.0.2
Could not find (undefined)

[unaor]

using @SantiPrll comment it worked for me

[SantiPrll]

@westdabestdb Si te fijas replique tu ejemplo y si trabaja, te recomiendo que resinstalar el CLI de forma global.

[josalvatorre]

As SantiPrII recommended, I reinstalled the angular cli globally. I'm still getting the "Could not find (undefined)" error after running both "ng new angular-website --version=7.0.4" and "ng new angular-website --version=7.0.2".
Does anyone know what "(undefined)" could be referring to?

[SantiPrll]

Que versión de node estás utilizando?

Que versión de node estás utilizando?

[StarDrop9]

I removed node_modules folder in users/{user name} and ng new [appname] now working.

[meysamsahragard]

Hi, For resolve this error uninstall @schematics/angular package or remove @schematics directory from node_modules directory then install a previous version. For example:
npm i @schematics/[email protected] --save-dev

[movadee]

node_modules

this solved my issue! thanx

[breningham]

I'm closing this issue as the original issue has been resolved.

[StephenWTurner]

I had the same error when I used underscores in the new app name instead of hyphens:

npm new my_new_app >>> Fails
npm new my-new-app >>> Succeeds

[vsanandan]

After trying all these things, I get the following error for the command
ng new getrequest --version=7.1.2

Tree type is not supported.

I am trying the above command on CLI.

Some time I get the error: Could not find (undefined)
I tried running as a super user (in Linux)

[MartinJohns]

I had the same error when I used underscores in the new app name instead of hyphens:

I had the same error when one of the name-parts was digits, e.g. prototype-1234. Changing it to prototype-s1234 works. So here it's a case of a bad regex.

[B1u2Pr0]

Hello, StephenWTurner
Thanks for your comment
Could you tell me the reason why it solves the issue?

[StephenWTurner]

Hi B1u2Pr0, I'm not sure it does solve the original issue at all. However, it allows a simple typo to be eliminated before getting unrelated 'me toos',

[SubbuSwaroop]

I was facing the same issue... The problem for me was , I was using an underscore when creating the directory name.
I was using "ng new Test_Angular". Then I changed it to "ng new Test-Angular" and it worked for me

[Mulperi]

I had the same error when I used underscores in the new app name instead of hyphens:
npm new my_new_app >>> Fails
npm new my-new-app >>> Succeeds

So it was the underscores. This worked for me. Thanks! (Still, it's strange)

[daton89]

in my case using @angular/cli 7.2.3

ng new angular-7-test failed with error

Schematic input does not validate against the Schema: {"name":"angular-7-test","version":"7.2.3","routing":true,"style":"scss"}
Errors:

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

ng new angular7testsuccess

[Rajkumar9386]

@meysamsahragard

npm i @schematics/[email protected] --save-dev

work for me
Thanks :)

[meysamsahragard]

@meysamsahragard

npm i @schematics/[email protected] --save-dev

work for me
Thanks :)

Hi dear Rajkumar. You're welcome.

[veera001]

@SubbuSwaroop Yes. i faced same issue and it was successful after removing uderscore
is there any specific usage for uderscore?

[aeros281]

I have the same error creating new project with underscore

ng new angular_wip
? Would you like to add Angular routing? Yes
? Which stylesheet format would you like to use? Sass   [ http://sass-lang.com   ]
Schematic input does not validate against the Schema: {"name":"angular_wip","version":"7.3.2","routing":true,"style":"sass"}
Errors:

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

Anyway to resolve this? It's ridiculous that the project must not contain underscore in order for the cli to successfully initialize the app.

[pacozevallos]

I removed node_modules folder in users/{user name} and ng new [appname] now working.

Eliminar la carpeta de node_modules funcionó para mí, había quedado un package.json que también lo eliminé.

[johnmanoahs]

Apparently if your project name has a "_" or "-" (underscore or hyphen) it tends to throw this error. I removed the special chars and it worked ok.

[royelias]

I had the same error when I used underscores in the new app name instead of hyphens:

npm new my_new_app >>> Fails
npm new my-new-app >>> Succeeds

had same issue and using hyphens instead of underscore worked perfectly

[alexbrtsv]

have the sane trouble

npm uninstall -g angular-cli
npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

reinstall helps me

[n8bizall]

I had this same issue and just had to make it
ng new myApp --version 7.3.6 <-the version of angular I am using

[aneeshjoshi]

🤦‍♂️ - This worked for me.

Thanks @johnmanoahs

[rafaelzuckerberg]

For me, before, I updated npm : "npm update" and after run : "ng new projetc-teste --version=7.3.6"

[mohanacchu]

i'm still facing the same issue.My current angular version is 7.3.6 but error still exist

ng new learn-curve
C:\Users\mohan.n\Desktop\My Help in Angular Nov\angular-learn>ng new learn-curve
Schematic input does not validate against the Schema: {"name":"learn-curve"}
Errors:

Data path "" should have required property 'version'.

i also tried ng new projetc-teste --version=7.3.6
for which i'm getting Cannot read property 'entries' of undefined

Please help me out

[chemc2]

@mohanacchu try no to use '-' on the name of the project. Something is wrong with newer versions in that regard

[rafaelzuckerberg]

Try inside your project to remove node_module and run npm install again

[farooqahmedkhan]

I had the same error when I used underscores in the new app name instead of hyphens:

npm new my_new_app >>> Fails
npm new my-new-app >>> Succeeds

Strange but this actually resolved the schematic issue.

[Cuica20]

For me, before, I updated npm : "npm update" and after run : "ng new projetc-teste --version=7.3.6"

Thanks, this worked for me.

[Sivaneymar07]

3 things you should check if you face problem on ng new
1) check the directory name - should not have alphanumeric and special characters.
2) type ng --version in node cmd, check whether all package is clear without showing error on the package version or else install those packages.
3) if cmd shows error on @angular\cli then delete c:\users\usernameAppdata\Roaming\npm\node_modules\@angular\cli and then install it, it will work. if you feel appdata is missing in the folder then it is in hidden, u should do C: -> Organize -> Folder Options -> View -> Hidden files and folder -> Show hidden files.....

Hope this will help you....

mine had alphanumeric. Removed the number and now its working. Ty

[yogeshdotnet]

HI,
This issue may be resolved by applying the following command in cmd.

npm i @schematics/angular@latest --save-dev

after applying this no need to write version after angular 7 project name just write
ng new ang-project-name

[rafmos]

I deleted the -3 at the end of my project name and then it worked. :)

ng new my-project-3 ----> Doesn't work
ng new my-project-three ----> Works

[crissdev]

It seems the CLI doesn't like project names that end with a dash/underscore and only digits (e.g app-name-01, app-name_02). Removing the dash/underscore works, ie. app-name01, app-name02.

[vip9]

For me, helped removing ~/package-lock.json (who knows why that file was in my home)

[alikarimii]

use --clientProject project-name flag work for me

[sagar87966]

previous CLI version:-- 7.3.8
solution:-- updated CLI version to the latest
use CLI version:- 7.3.9
work for me

[iappwebdev]

In my case i had an app anem like abc-2-xyz. Changing it to abc2xyz resolved the problem.

[Nocturnal-2]

I was getting this error when I had an _underscore_ sign in my project name. Worked normally after removing it.

Angular CLI: 7.3.8

[inajad]

I had the same error when I used underscores in the new app name instead of hyphens:

npm new my_new_app >>> Fails
npm new my-new-app >>> Succeeds

this one worked fine for me.
Thanks.

[vrathaure]

Resolved as follows:-

npm uninstall -g @angular/cli
npm uninstall @angular/cli
npm cache verify
npm install -g @angular/cli@next
npm install @angular/cli@next
npm i @schematics/angular@next

[Anand-Chavan]

first type ng -v
then according to your version install following command
@schematics/[email protected]

[dsun-ge]

I had the same problem with ng new naq_monthly_settlement_report. I fixed it with ng new naq-monthly-settlement-report
