Answer 1

Try to execute export PATH=$PATH:/mnt/c/Windows/System32. Change the path /mnt/c/ to the path mounted on your wsl Windows (mount).

if it works, insert the path /mnt/c/Windows/System32 into the file /etc/environment.

here in my case this solution worked

downgrading react-scripts to npm install react-scripts@2.1.8 works for me

Answer 3

If your system is windows, set your environment variable, add %SystemRoot%\system32 to your PATH I met this error yesterday，hope it works to you. Don't forget reboot you PC

Answer 4

I faces this issue while using the windows subsystem for Linux and solved it by adding C:\Windows\System32 to Environment Variables Path. Environment Variables can add as follow.

go to

control panel -> System and Security ->System -> Advanced System Settings.

From the appearing dialog box, select Environment Variables, and then under System Variables select the path and select edit and add C:\Windows\System32. Restart the machine.

Answer 5

in my case react-scripts was missing from the devDependencies adding it in devDependencies resolved it for me. Hope this helps
