react-native - 安装 ReactNative CLI 时出现 NPM 安装错误

问题描述

我希望将 React Native CLI 安装到我的 Windows 10 x64 PC。请帮忙。

发出此命令时遇到以下错误：

npm install -g react-native-cli

我收到的错误：

解决方案

此问题可能与您的代理有关，首先，请尝试以下命令：

npm config set proxy null
npm config set https-proxy null
npm config set registry http://registry.npmjs.org/

然后执行

npm install -g react-native-cli

希望这会有所帮助。
