我已经安装了 Nodejs、Java、Python 和 android studio，并按照以下命令安装了 create-react-native-app
npm install -g create-react-native-app
之后我就跑
sudo create-react-native-app MyFirstNative
但出现错误
我已经更新了 npm、expo-cli 等，甚至使用 sudo 命令也会出现权限错误
azad@azadhussain:/var/www/html/githubrepo$ sudo create-react-native-app MyFirstNative

答案1
我通过更改 .npm 目录的权限解决了这个问题。我进入了 npm 全局目录，它位于
/home/<user-name>
我通过输入此命令进入了该目录
cd /home/<user-name>
然后通过输入此命令更改.npm 文件夹的权限。
sudo chmod -R 777 ".npm"
对我来说，这个方法非常有效。但是，这种方法存在安全漏洞，也就是说，你的全局包目录可供所有层级访问。

对我自己来说，这是因为我使用的是旧版本的 Node（v8.11.3），而稳定版本（截至目前）是 v14.15.4。
我的解决方法是通过下载最新的稳定版本来更新 Node。
