在windows 10中安装expo-cli将导致错误。
提问于 2020-04-24 00:47:50
我在windows 10上安装了NodeJSv12.16.2来使用react-本机是用来学习东西的，所以不需要安装android或xocde。正如我在react本机文档中看到的那样，最简单的方法是使用expo-cli，我使用以下命令将其安装在我的计算机上，但它无法工作：
$ npm install -g expo-cli
$ npm install expo-cli --global
$ yarn add global expo-cli所有这些命令都会导致错误，我遗漏了什么，以及如何解决这个问题。以下是问题的细节：
npm install expo-cli --global npm WARN deprecated joi@14.0.4: This version has been deprecated in accordance with the hapi support policy (hapi.im/support).

由于使用npm的optionalDependencies安装适用于平台的ngrok包，您所看到的警告是不可避免的，所以不要担心这一点。与您相关的错误是“near！在解析接近.时JSON输入意外结束”--关于这个主题有很多相关的文章，它们通常建议您做以下工作：
清除npm缓存npm cache clean --force
- Run
npm i -g expo-cli
