Tried to solve by deleting all npm packages, cleaning npn cache, reinstalling Node.js and the problem persists. I have also tried to use cmd instead of Windows Powershell with no success

[SiriusFuenmayor]

This is a problem only with Windows 10 because I have follow the instructions in Ubuntu and everything works fine. I do not have the experience to figure out what is happening, I have tried with the LTS version of Node and the lastest version and nothing works. If someone knows the cause I will appreciate its help.

@SiriusFuenmayor I tried to Google for your error but couldn't find similar errors... Could you try using Git Bash and see if that solves it? https://gitforwindows.org/

[SiriusFuenmayor]

Hi, yes let me try and I will tell you

[SiriusFuenmayor]

same error

[chibicode]

@SiriusFuenmayor hmm ok, the only relevant issue might be this one: https://github.com/facebook/create-react-app/issues/8441#issuecomment-583197435

npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe"

Alternatively you could check if your ComSpec or PATH enviromental variables includes C:\Program Files (x86)\git\bin\bash.exe' value and replace it with path to your actual shell executable

[SiriusFuenmayor]

Thank you so much for your time @chibicode, let me see if it works.

[SiriusFuenmayor]
