Hi @jean-luc_TOUZALIN_86495,

Please take a look at the following post:

Let me know if that solves your issue.



Well I just use winrar to unzip to a folder.
After I adapt dotenv_windows and rename to .env
How can I be sure that the file .env is used ?


Write this on .bablerc
“presets”: [
“plugins”: [

Write this on .eslintrc


“extends”: [“react-app”, “prettier”],
“rules”: {
“jsx-a11y/href-no-hash”: “off”,
“jsx-a11y/anchor-is-valid”: [“warn”, { “aspects”: [“invalidHref”] }]

Writethis on .prettierrc
“useTabs”: false,
“printWidth”: 80,
“tabWidth”: 2,
“singleQuote”: false,
“trailingComma”: “all”,
“parser”: “babylon”,
“semi”: false

All thee files should be written at project root.

I had the same issue as well on Windows 10. I am not sure why the initial zip extraction did not copy the files .babelrc;.eslintrc;.prettierrc, but once those files were added to the project root the application started fine.
