错误：当尝试从文件C:\Users\byambadorj\Desktop\LoginEx\src\LoginScreen.js解析模块native-base时，成功找到了包C:\Users\byambadorj\Desktop\LoginEx\node_modules\native-base\package.json。但是，此包本身指定了无法解析的main模块字段（C:\Users\byambadorj\Desktop\LoginEx\node_modules\native-base\src\index。实际上，这些文件都不存在C：\Users\byambadorj\Desktop\LoginEx\node_modules\native-base\src\index（.native|.android.js|.native.js|.js|.android.json|.native.json|.json|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx）
