无法将"expo"识别为内部或外部命令 [英] 'expo' is not recognized as an internal or external command

问题描述

在运行npm install -g expo-cli并成功地全局安装软件包之后，仍然无法将expo识别为内部或外部命令.有谁知道我如何使用Windows 10来解决此问题，或者如何处理诸如path变量之类的问题.

After running npm install -g expo-cli and successfully installing the packages globally, expo is still not recognized as an internal or external command. Does anyone know how I might get around this issue using windows 10, or what to do in terms of something like a path variable.

推荐答案

对于Windows 10，您只需将npm文件夹添加到路径环境变量中即可.

For Windows 10, you can simply add the npm folder to your path environment variable.

1. 按Windows键并搜索Environment variables.
2. 在System variables下的 Path 变量中，添加一个新 内容为(不带/node_modules )的条目:

1. Hit Windows key and search for Environment variables.
2. Inside the Path variable under System variables, add a new entry with this content (without /node_modules ):

%USERPROFILE%\AppData\Roaming\npm

1. 打开新的命令提示符，然后输入

> expo

您将看到以下内容:
