[英]Can't install expo-cli -g
我是 react-native 的新手,当我尝试启动npm start
命令时,我正在尝试在所有 package 安装后设置我的项目,然后显示'expo-cli' is not recognized as an internal or external command,
错误。
好的,那么我已经按照这里的指南进行操作
之后我以这种方式添加了我的env path
:
environment variable > System Variables > PATH >
C:\Users\YOUR_USERNAME\AppData\Roaming\npm
然后我必须再次安装:
npm install -g expo-cli
但它对我不起作用,我不知道为什么。
当我尝试运行此命令npm install -g expo-cli
然后显示如下错误:
PS C:\Users\alami\OneDrive\Desktop\React native\starter-react-native> npm install -g expo-cli

至少我刚刚以这种方式解决了我的问题:
cmd
npm i -g expo-cli
我刚刚解决了我的问题。
