Xcode 反应本机错误：解析不明确

当我尝试在iOS模拟器上运行React本机应用程序时，我会看到一个红色屏幕，显示以下错误：

不明确的解决方案：模块 “/Users/my user/Documents/my RN app/app/index.js”尝试要求 “反应本机矢量图标”，但有几个文件提供 这个模块。您可以删除或修复它们：

/Users/my user/Documents/my-RN-app/ios/build/build/Products/Debug-iphonesimulator/MyApp.app/my-RN-app/node\u modules/react-native/local-cli/core//uuu装置/uu文件/package.json

/用户/my user/Documents/my RN app/node_modules/react native/local cli/core/__fixtures___/files/package.json

但是，上面两个文件（package.json文件）都丢失了。我以前确实遇到过这个错误，所以我决定删除上面提到的第一个目录位置（在ios/build/.etc下）中的package.json文件，并刷新应用程序，然后就可以正常加载了。现在，在尝试在iOS模拟器中再次启动我的应用程序后，我返回到相同的错误，但我无法删除package.json文件，因为它现在在两个位置都不存在

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卡，但仍然出现错误

最后，我尝试了以下方法：

sudo rm-rf node_模块

（如果我不使用

sudo

，我会得到“权限被拒绝”，尽管我似乎对此项目中的所有文件/文件夹拥有完全的读/写权限）

sudo rm-rf ios/build

npm安装

cd-ios&&pod安装

react本地链接

然后回到Xcdoe:Product>Clean，之后我再次运行模拟器。还是一样的错误

我必须手动将React pod链接到

节点\u模块

：

pod'React'，：path=>'../node\u模块/React native'

---

然后清理并重新构建

发布你的

包.json

。也要考虑阅读。特别是，请检查，因为该问题可能与您遇到的问题有关。请尝试

npm start--reset cache

Michael：我已经在上面发布了我的

package.json

，但是您链接到的注释可能会有所帮助（它没有解决问题，但我还是删除了它建议的文件，然后运行下面的命令，现在我很好）.Mukesh：我试着运行这个命令，它似乎成功了。下面是我运行的命令，顺序是：

rm-rf ios/build

pod install

react native link

，最后是

npm start--reset cache

，然后我启动了sim卡，没有错误，耶！Nvm，说得太快了。应用程序启动了，然后我启动了ied也启动了远程调试器，现在我得到了一个类似的错误，除了现在使用

尝试要求使用react native

而不是

react native vevector icons

。我打开了xcode并进行了产品>清理，试图通过xcode（而不是react native cli）启动应用程序现在它开始工作了…我对根本问题到底是什么感到困惑。我遇到了一个类似的问题，这可能会有所帮助？太棒了，但我发现我还需要添加一个SubSecs部分！
