Fixex in System Variable there was ComSpec variable to %SystemRoot%\system32\cmd.exe;
I removed ";" and all works now!
Thanks to all

@pindaroli i had to downgrade to 0.9.x to get it working. perhaps its an issue with the module's own dependencies.

jpalomar on 19 Mar 2018

@jpalomar I downgrade [email protected] but I have the same problem

pindaroli on 19 Mar 2018

@pindaroli try npx create-react-app myapp

bondz on 19 Mar 2018

Try upgrading node, npm uninstall -g create-react-app and then use npx like @bondz is suggesting above.

andriijas on 20 Mar 2018

@bondz the error is the same with npx

pindaroli on 20 Mar 2018

@pindaroli True. That command makesnpx use the already installed version of CRA that wasn't working for you.

Try this instead

npx -p create-react-app -c 'create-react-app myapp'

bondz on 21 Mar 2018

Hi! I tried:

npx -p create-react-app -c 'create-react-app myapp'

output:

C:\Users\olindo.js\test>npx -p create-react-app -c 'create-react-app myapp'
"CALL "C:\Program Filesnodejs\node.exe" "C:\Program
Filesnodejs\node_modules\npm\binnpx-cli.js" prefix -g" non è
riconosciuto come comando interno o esterno,

spawn C:\WINDOWS\system32\cmd.exe; ENOENT

Thanks

@pindaroli I think your installation of NodeJS might be corrupt. Try uninstalling nodejs, and downloading and installing a fresh LTS copy from https://nodejs.org

bondz on 24 Mar 2018

I'll close this because there's nothing we can help with here. Please file a support ticket with npm and try a full reinstall of your Node environment.

@pindaroli

can you please let me know from which file did you removed the trailing ; as you mentioned above as I am also facing similar issue while using the create-react-app command to create an app.

Thanks,
Arup Chandra Dawn

Control-Panel->SystemProperties-Envirovment Variables->System Variables

"ComSpec" variable edit and look if there is a trailing ";" in definition.
