不能在 Windows 上使用 expo 和 expo-cli

Question

我尝试在全局范围内安装 expo-cli 和 npm：

$ npm i -g expo-cli

当我尝试时，我收到了一些关于弃用的警告：

虽然看起来安装成功了。

问题是当我想使用expo init something 时，bash 说它无法识别它。

我该如何解决？

环境：

操作系统：Windows 10

终端：Git Bash

您可能需要手动将 npm 文件夹添加到您的环境变量中。 您可以按照以下步骤执行此操作：

1. 打开开始并搜索环境变量。
2. 在系统变量下的路径变量中，添加： %USERPROFILE%\AppData\Roaming\npm
3. 保存并退出
4. 打开一个新终端并输入您的命令。希望它应该可以工作。
