Javascript react节点依赖项安装破坏了我的react本机应用程序

我通过使用“npm安装--保存react原生元素”将react原生元素添加到我的项目中，但它破坏了我的项目。我找不到正确的解决办法。我不知道怎么解决这个问题

安装react本机元素后， 我收到一个错误“error:React Native未安装。请在项目目录中运行

npm install

。 [21:03:06]无法启动项目。请修复错误并重新启动项目。 [21:03:06]在环境中设置EXPO_DEBUG=true以查看堆栈跟踪。“

这是我第一次在stackoverflow上发布问题。如果我犯了什么错误，我很抱歉

My project should have worked fine but it actually started giving me bad errors

---

最初，当世博会成立时，它使用纱线。如果使用npm安装软件包，npm可能会删除由Thread安装的软件包，因为没有

package lock.json

您可以通过运行

npmi

来修复此问题，它应该重新安装已删除的依赖项

---

您应该使用

纱线

或

npm

而不是两者的组合，因为这可能会导致问题

我也遇到了同样的问题，运行“npm审核修复程序”

---

为我修好了。希望它能有所帮助

尝试运行以下命令：npm install--save react native cliSo，当它询问“找到了Thread v1.12.3。使用Thread安装依赖项？”时，我需要选择“否”？命令可能解决了这个问题。世博会开始运行没有问题，但我会尝试与我目前的项目，如果它工作。谢谢..您可以使用

spirn

，但请注意，如果使用

npm

，您可能需要使用

npm i

重新安装所有依赖项。正如我所说，选择一个并坚持下去。
