I also got the issue with

I get the same issue also.

I can not create a new workspace with ng new in windows10

This usually means that the resolved cwd path is invalid, or the cmd path is incorrect.

If you do execute pwd and where cmd in the terminal where you are trying to do ng new what is the output?

[Li-Mark]

@alan-agius4
As your tips, when I got your reply.
First, I restarted the PC and created a new project with powershell, there isn't any issue.

Then I tried to create another project with cmd, it can be also created.

That's so weird. The issue is gone. I don't know why.

[grebneglig]

Thanks @alan-agius4 i could resolve for me.
I tried to create an project in "D:" and got the same error as @MangoWHL.
Then i created a project in "D:\Test" and all was ok.
So i think the Problem was the Path.

[lranders]

I can reproduce the exact same behavior on Windows 10 as @grebneglig,
if I try ng new in the root of any of my drives.
Make and enter a folder, and the error goes away.

[hexl84]

Thanks @grebneglig @lranders , I create a folder under the root of the driver, then ng new under the folder, it works.

[Exocomp]

I get the same issue when creating a project on root of a drive for example:

R:\

Create a project one level deep works:

R:\test

ng --version

Angular CLI: 7.0.3
Node: 8.9.4
OS: win32 x64

[aaymont]

Can also confirm failing with the same error when trying to create a new project from the root directory of a drive on Windows 10, but works if it's inside a sub-directory.

[amirzenoozi]

I get the same issue when creating a project on root of a drive for example:
F:\
Create a project one level deep works:
F:\TestDirectory
But i want to create project on root of a driver
how can i ?

[adamdport]

@amirzenoozi create the project one level deep and then move it?

[alan-agius4]

Hi all, we have identified the bug that is causing this error, as at the moment we are not handling root paths correctly in windows.

We landed a PR #12951 to fix the issue.

[TahirMehmood]

i am getting same issue but not in root drive
e:\code\FrontEnd\Angular-by-bradtraversy
still getting same error
