reactjs - Babel 5 插件正在使用不受支持的 Babel 版本运行

Question

在我使用yarn add -D babel-plugin-react-relay安装relay-query插件后，并在运行开发服务器后，我收到此错误:

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")
    at Array.reduce (<anonymous>)

这是我的package.json 文件:

如何解决这个问题？

Answer 1

由于您使用的是react16，因此无需弹出即可添加自定义环境变量。您的自定义环境变量在脚本中必须以 REACT_APP_ 开头。这将解决兼容问题。
