确定.由于我本人花了几个小时才解决此问题，所以希望我能为同样有此问题的人们提供帮助.

OK. Since I myself spent a few hours before solving this, I hope I can help you guys who also have this problem.

要将styled-jsx与create-react-app一起使用，您需要:

To use styled-jsx with create-react-app, you need:

1. 纱线添加react-app-rewired custom-cra
2. 替换为package.json

    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",

使用

    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",

1. 创建(在根目录中， package.json 旁边)文件 config-overrides.js

1. create (in root directory, next to package.json) file config-overrides.js

{ override, addBabelPlugin, addBabelPreset } = require('customize-cra');
module.exports = override(
    addBabelPlugin('styled-jsx/babel')
);

1. 在根目录文件中创建 .babelrc (仅在运行 jest test 时使用)

1. create in root directory file .babelrc (it is only used when you run jest test)

{
    "plugins": ["styled-jsx/babel"]
}

1. 在您的 index.js 中(或将React装入DOM的位置)，在调用ReactDOM.render(....)之前，插入以下代码，取自 https://github.com/vercel/styled-jsx/issues/560#issuecomment-599371026

1. in your index.js (or where it is you mount React into DOM), before calling ReactDOM.render(....), insert the following bit of code, taken from https://github.com/vercel/styled-jsx/issues/560#issuecomment-599371026

const _JSXStyle = require('styled-jsx/style').default;
if (typeof global !== 'undefined') {
    Object.assign(global, { _JSXStyle });
}

这是不幸的，但是没有它，这种复杂的配置会有些变幻.

It is unfortunate, but this complex configuration is a bit fickle without it.

仅当将 yarn build 或 yarn test 与create-react-app一起使用时，才需要执行步骤4和5.

You need steps 4 and 5 only if you use yarn build or yarn test with create-react-app.
