Question

用relay-query安装yarn add -D babel-plugin-react-relay插件后，运行开发服务器后，出现此错误：

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")

这是我的package.json文件：

如何解决此问题？

Answer 1

我认为对graphQL进行了升级，但未在中继中应用。因此，要运行react应用程序，您可以使用以前的版本：

"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 2

由于您正在使用react16，因此无需弹出添加自定义环境变量。您的自定义环境变量必须在脚本中以 REACT_APP _ 开头。这样可以解决兼容问题。

    {
  "name": "tictacturing",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.6.3",
    "react-dom": "^16.6.3",
    "react-router": "^3.2.1",
    "react-scripts": "2.1.1"
  },
  "scripts": {
    "start": "REACT_APP_GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjoyiidl5gzv901148dsyafg1 react-scripts start",
    "build": "REACT_APP_GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjoyiidl5gzv901148dsyafg1 react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "devDependencies": {
    "babel-plugin-react-relay": "^0.10.0"
  }
}

Answer 3

您应该通过npm安装babel而不是如下所示的纱：

npm install -D babel-plugin-react-relay

Babel 5插件正在使用不受支持的Babel版本运行
