创建React Native应用时出现错误

Question

我已经安装了Nodejs，Java，Python和android studio，并通过以下命令安装了create-react-native-app

npm install -g create-react-native-app

那之后我正在跑步

sudo create-react-native-app MyFirstNative

但出现错误

我已经更新了npm，expo-cli等，甚至将命令与sudo一起使用，甚至出现权限错误

我通过更改.npm目录的权限解决了此问题。我去了npm全球目录，

/home/<user-name>

我通过输入此命令进入该目录

cd /home/<user-name>

，然后通过输入此命令来更改.npm文件夹的权限。

sudo chmod -R 777 ".npm"

对我来说，它就像是一种魅力。但这存在一个安全漏洞，即您的全局软件包目录可用于所有级别。
