Question

我正在尝试使用react-native和expo在Windows 8.1上开发我的第一个Android应用程序进行测试。

从一个教程开始，我有一个使用react-native组件的工作项目，但是当我使用

安装依赖项时，一切都崩溃了

`npm install --save react-navigation`:

npm-start返回了

错误：未安装React native。请在您的项目目录中运行“ npm install”。

所以我按照建议再次运行了npm-install。
这导致npm-start询问我是否要全局安装expo-cli，是否回答是或否，但出现以下错误：

Installing the package [expo-cli][1]...

我搜索了StackOverflow，并按照建议处理了this answer中发现的ELIFECYCLE个错误。运行npm cache clean，然后删除node_modules目录和package-lock.json，但错误是相同的。
我什至尝试执行这些步骤，以及在再次运行react-navigation之前从我的package.json文件和代码中的依赖项中删除npm-install，但是它没有任何改变。

有趣的是，在单独运行expo start时，它设法在浏览器中启动捆绑程序和devtools只是没有正确的IP地址。

我也不知道这是否重要，但是在运行npm-install时我有2个漏洞，当我运行npm-audit时表明lodash软件包中的'Prototype Pollution'漏洞很低ws软件包中的“拒绝服务”漏洞很高。但是即使运行npm audit fix

，也没有任何改变

无论如何，希望您能帮助我，谢谢！

Answer 1

我遇到了同样的问题。

如果您运行：

npm i expo-cli

然后

npm start

它将起作用

Answer 2

在我的情况下，未安装angular-cli，因此我以-

的身份运行命令

npm install -g angular-cli

react-native节点依赖性安装中断了项目
