xcode – React Native Error：模糊分辨率

2019年7月28日 201次阅读

当我尝试在iOS模拟器上运行我的React Native应用程序时,我看到一个红色屏幕,出现以下错误：

Ambiguous resolution: module
‘/Users/my-user/Documents/my-RN-app/app/index.js’ tries to require
‘react-native-vector-icons’, but there are several files providing
this module. You can delete or fix them:

/Users/my-user/Documents/my-RN-app/ios/build/Build/Products/Debug-iphonesimulator/MyApp.app/my-RN-app/node_modules/react-native/local-cli/core/__fixtures__/files/package.json

/Users/my-user/Documents/my-RN-app/node_modules/react-native/local-cli/core/__fixtures__/files/package.json

但是,上述两个文件(package.json文件)都丢失了.我之前实际上遇到过这个错误,所以我决定在上面提到的第一个目录位置(在ios / build / ..等下面)删除package.json文件并刷新应用程序,它加载得很好.现在,在尝试再次在iOS模拟器中启动我的应用程序后,我又回到了同样的错误,但是我无法删除package.json文件,因为它现在甚至都不存在于任何一个位置.

我试图在我的app / index.js文件中注释掉react-native-vector-icons lib的导入并重新启动sim,但错误仍然出现.

最后,我试过这个：

> sudo rm -rf node_modules(如果我不使用sudo,我得到“权限被拒绝”,虽然看起来我对这个项目中的所有文件/文件夹都有完全的读/写权限)
> sudo rm -rf ios / build
> npm安装
> cd ios&& pod安装
> react-native链接

然后回到Xcdoe：产品>清洁,然后再次运行模拟器.还是一样的错误.

根据要求,这是我的package.json文件：

  }
}

最佳答案 我不得不手动将React pod连接到node_modules：

pod’React’,：path => ‘../node_modules/react-native’

然后清理并再次构建
