创建react本机应用程序时出现错误

Question

我已经安装了Nodejs、Java、Python和android studio，并安装了create-react-native-appby命令

npm install -g create-react-native-app

在那之后，我要跑步

sudo create-react-native-app MyFirstNative

但是得到了错误

我已经更新了npm、expo-cli等命令，甚至将命令与sudo一起使用时也会出现权限错误

azad@azadhussain:/var/www/html/githubrepo$ sudo create-react-native-app MyFirstNative

我通过更改我的.npm目录的权限解决了这个问题。我访问了npm全局目录，它位于

/home/<user-name>

我通过输入以下命令转到此目录

cd /home/<user-name>

然后通过输入以下命令更改了.npm文件夹的权限。

sudo chmod -R 777 ".npm"

它对我来说就像是一种魔力。但这有一个安全缺陷，即所有级别都可以访问您的全局包目录。
