/node_modules/@react-native/polyfills/error-guard.js:14
type ErrorHandler = (error: mixed, isFatal: boolean) => void;
^^^^^^^^^^^^
SyntaxError: Unexpected identifier
at Runtime.createScriptFromCode (node_modules/jest-runtime/build/index.js:1350:14)
at Object.<anonymous> (node_modules/react-native/jest/setup.js:469:6)
However, I have already set
transformIgnorePatterns": [
"node_modules/(?!(jest-)?react-native|react-(native|universal|navigation)-(.*)|@react-native-community/(.*)|@react-navigation/(.*)|bs-platform|(@[a-zA-Z]+/)?(bs|reason|rescript)-(.*)+)"
transformIgnorePatterns": [
"node_modules"
I have set babel properly like
module.exports = function (api) {
api.cache(true);
const presets = ['@babel/preset-env', '@babel/preset-react'];
const plugins = ['@babel/plugin-proposal-class-properties'];
return {
presets,
plugins,
and I have already tried clearing the cache.
Does anyone have any idea?
Add @react-native
to your Jest configuration. Such as:
transformIgnorePatterns : [
"node_modules/(?!(jest-)?@react-native|react-(native|universal|navigation)-(.*)|@react-native-community/(.*)|@react-navigation/(.*)|bs-platform|(@[a-zA-Z]+/)?(bs|reason|rescript)-(.*)+)"
