参考：可以找到变量：需要博览会

Question

我在博览会项目中遇到了这个错误

ReferenceError: Can't find variable: require
at node_modules/react-native/Libraries/Core/ExceptionsManager.js:95:4 in reportException
at node_modules/react-native/Libraries/Core/ExceptionsManager.js:141:19 in handleException
at node_modules/react-native/Libraries/Core/setUpErrorHandling.js:24:6 in handleError
at node_modules/@react-native/polyfills/error-guard.js:49:36 in ErrorUtils.reportFatalError

at http://192.168.1.228:19000/node_modules/expo/AppEntry.bundle?platform=android&dev=true&hot=false&minify=false:479020:3 in global code

I tried the fixes I could find but none of them worked for me. I tried clearing the cache, creating a new project and copy and pasting the file of the existing project but I still get the same issue. Any help is much appreciated
