创建react本机应用程序时出错

Question

我已经安装了Nodejs、Java、Python和android，并安装了如下命令

npm install -g create-react-native-app

从那以后我就开始跑步

sudo create-react-native-app MyFirstNative

但犯了错误

我已经更新了npm、expo-cli等，甚至使用sudo命令，甚至获得了权限错误。

我通过更改.npm目录的权限来解决这个问题。我去了npm全球目录

/home/

通过输入以下命令，我转到了这个目录

cd /home/

然后通过输入此命令更改.npm文件夹的权限。

sudo chmod -R 777 ".npm"

对我来说就像一种魅力。但是存在一个安全漏洞，即您的全局包目录可以访问所有级别。
