Babel 5 plugin is being run with an unsupported Babel version - reactjs

Question

After I installed relay-query plugin with yarn add -D babel-plugin-react-relay, and after running the dev server, I get this error:
Error: [BABEL] /Users/nemanja/sites/tictacturing/src/index.js: The (relay-query) Babel 5 plugin is being run with an unsupported Babel version. (While processing: "/Users/nemanja/sites/tictacturing/node_modules/babel-plugin-react-relay/lib/index.js")

How to resolve this issue?

Answer 1

Since you are using react16 there is no need to eject to add the custom environment variable. Your custom environment variable must begin with REACT_APP_ in your script. This will solve the compatible issue.

Answer 2

I think there is an upgrade for graphQL that is not applied in relay.
so for running the react application, you can use the previous version:
"scripts": {
"start": "GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cixqegi9u003g0196b2rtnhqu node scripts/start.js",
"build": "GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cixqegi9u003g0196b2rtnhqu node scripts/build.js",
"test": "node scripts/test.js --env=jsdom"

Answer 3

you shoud install babel by npm instead of yarn like below:
npm install -D babel-plugin-react-relay
