Unexpected error upon creating a new Project

Is this a bug report?

Yes

Did you try recovering your dependencies?

No, everything is up-to-date, and it is a NEW project.

Which terms did you search for in User Guide?

None, since it is a "start" of a project.

Environment

1. node -v: v8.9.4
2. npm -v: 5.6.0
3. yarn --version (if you use Yarn): 1.6.0
4. npm ls react-scripts (if you haven’t ejected): `-- (empty)

Then, specify:

1. Operating system: Windows 10
2. Browser and version (if relevant): N/R

Steps to Reproduce

(Write your steps here:)

1. Install Node/NPM
2. Install create-react-app (npm install -g create-react-app)
3. Create a new Project (create-react-app dashboard)

Expected Behavior

Create a new Folder with the project inside.

Actual Behavior

source $ create-react-app dashboard

Creating a new React app in ~\Projects\test\source\dashboard.

Reproducible Demo

Since there is no way to create the Project, it is not possible to build a "demo".

Thanks in advance, and keep up the amazing work!

[Timer]

Are you using the standard npm registry?

@Timer yes, it just "started" happening today, as I upgraded to the latest version of CRA.

source $ create-react-app --version
1.5.2

Thanks.

[Timer]

Odd, can you try using npx instead like in our README?

[gaearon]

I wonder if any transitive updates released new versions recently. Maybe something upstream related to waiting for a process to finish broke.

@Timer
Using npx produced the same result:

@gaearon
Anything I could do to help on this thought?

[gaearon]

Can't reproduce on macOS on these versions.

Is there anything special about your Windows environment? Why do paths start with ~?

@gaearon
Nothing special, the only thing "different" is that everything is installed with Scoop.
The "~" were to just omit the home folder. and it is "C:\Users\julio".

About 2 days ago, with this very same environment, I created a Project, with no errors.

[gaearon]

I see. Maybe worth trying to test with Scoop specifically.
I can give it a try to reproduce some time later this or next week.

If you run with --use-npm, does the problem persist?

@gaearon
Running with --use-npm succeeded.

Maybe it is an issue with yarn (installed with Scoop).
I'll try and install it from npm, and get back to you ASAP.

Returning to yarn from Scoop, brought the error back.
I believe there's a difference in the "official" yarn distribution regarding the npm one.

Since I am not an expert, I cannot tell exactly what it is. But I am available to help with anything.

[Edit]
Browsing from Google, I stumbled int this old issue (#2751).

[Edit2]
Just posted a comment on the Yarn issue tracker, so I think this one could be closed, since it appears NOT to be an issue with react-scripts per se, or even with npm.
