The solution by @xiaobowas actually insufficient for me. It took me a while to figure this out after upgrading expo to v32, so here's what I did in case anyone else has the same problem. (Answer from expo forums.)
@xiaobo的解决方案对我来说实际上是不够的。将 expo 升级到 v32 后，我花了一段时间才弄清楚这一点，所以这是我所做的，以防其他人遇到同样的问题。（来自世博论坛的回答。）
If you have a .babelrcfile in the root of your repository, re-name it to something like .babelrc-oldso it doesn't get used.
如果您.babelrc的存储库的根目录中有一个文件，请将其重命名为类似名称，.babelrc-old以免被使用。
Add a file called babel.config.jsto the root of your repository.
添加一个名为babel.config.js您存储库根目录的文件。
Put this in the babel.config.js file:
把它放在 babel.config.js 文件中：
module.exports = function(api) {
api.cache(true);
return {
presets: ['babel-preset-expo'],
};
};
All set!
可以了，好了！

After you execute npm run eject:
执行后npm run eject：
cd /your/project/path(ignore)rm -rf node_modulesnpm install(don't use yarn )npm run start success
cd /your/project/path（忽略）rm -rf node_modulesnpm install（不要使用纱线）npm run start success

In my case, it was solved by installing, on Reactjs, "@babel", @babel/plugin-transform-react-jsx
就我而言，它是通过在 Reactjs 上安装“@babel”来解决的， @babel/plugin-transform-react-jsx
1: yarn add @babel/plugin-transform-react-jsx
2: yarn start
1: yarn add @babel/plugin-transform-react-jsx
2:yarn start
