@super918180 I fixed this issue with following steps:

  • Install @babel/plugin-proposal-decorators
  • Change .babelrc https://pastebin.com/QdddctRN

But I'm not sure that it is right way.

if you are using latest rn,the rn-cli.config.js should be like this module.exports = { transformer: { babelTransformerPath: require.resolve('react-native-typescript-transformer'), }, }; you can follow the metro-bundler document https://facebook.github.io/metro/docs/en/configuration

It's work for me!

Installing these two plugins and updating babel.config.js seems to be working for me:

  "plugins": [
    ["@babel/plugin-proposal-decorators", { "legacy": true }],
    ["@babel/plugin-proposal-class-properties", { "loose" : true }]
  ]

Error: Support for the experimental syntax 'decorators' isn't currently enabled Issue: I'm currently experiencing an issue with Babel when trying to use decorators in my JavaScript code. I've followed the official Babel documentation and created a .babelrc.json file with the necessary configuration, but I'm still getting the error

hers is .babelrc.json { "presets": ["@babel/preset-env", "@babel/preset-react"], "plugins": [ "@babel/plugin-transform-runtime", ["@babel/plugin-proposal-decorators", { "legacy": true }], ["@babel/plugin-proposal-class-properties"] ] } How to resolve this
