expo安装<package>在Ubuntu18.04上失败

Question

我在使用expo启动这个react原生应用程序时遇到了一些麻烦。我不能使用npm安装expo-cli，所以我决定使用Yarn。经过yarn的一些错误后，它终于解决了，但现在我不能添加任何包到项目中使用expo install。

下面是我运行的命令：

expo install react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view

来自react-navigation tutorial

但是我得到了以下输出：

yarn add v1.22.4

尽管该错误指出这是权限问题，但使用sudo运行该命令并不起作用。

导致此错误的原因可能是什么？

我也遇到了这个问题，似乎是因为通过snap安装了node.js。关于snap环境中文件权限的一些问题，尽管我不完全确定为什么npm和yarn可以正常工作，但在通过expo运行时就不能正常工作

卸载node的snap版本并通过apt安装为我解决了这个问题，如果您想要比Ubuntu apt存储库支持的更高版本的node，那么有一个很好的tutorial here
