  • Unfortunately I'm unable to repro the issue on a clean pull of the basic-sample-react sample. I tried installing dependencies via both yarn and npm install. Based on the error message, it sounds like there may have been an issue installing the babel-preset-env module. Can you zip up your basic-sample-react folder (including the node_modules folder) and send us a link to download - [email protected]?

  • Also, what version of node.js and npm / yarn are you using?

It looks like an npm install gone bad as there are several dependencies missing from the node_modules folder. Can you share what version of node.js and npm you're using? Other than that, I would suggest deleting the node_modules folder and the package-lock.json file and running npm install again. Or, just run npm install again (that worked for me locally on your project).

  • It worked now the application is loading :) thank u Mar 2, 2018 at 19:26

You can try the following commands one by one, these are the dependencies which are not added by default, but are required:

npm install -g ng-cli

npm install -g angular-cli

npm install -g @sitecore-jss/sitecore-jss-cli

npm install

npm start

Just installed the JSS. if those fails try npm update -g
