  • 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?

Reset to default

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).

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
