react-native -bash：react-native：找不到命令

Question

我安装节点和守望者

 brew install node
 brew install watchman

npm install -g react-native-cli

但是当我使用react-native初始化测试

我有错误： -bash：react-native：找不到命令

Answer 1

第一
       sudo npm install -g react-native-cli

此命令输出路径如下

/usr/local/bin/react-native -> /usr/local/lib/node_modules/react-native-cli/index.js

然后（用于上面的路径示例）

export PATH="/usr/local/lib/node_modules/react-native-cli/index.js"

react-native init appName

Answer 2

尝试：sudo npm install -g react-native-cli

或 npx ，然后以npx react-native init demo
