Answer 1

您在/usr/local/lib/node_modules 中的全局节点模块存在权限问题

很可能您之前做过类似sudo npm install -g ... 的操作，它已将软件包安装为root，而这些软件包现在只能由root 更新或删除。您可以继续运行 sudo 来安装全局软件包，但出于安全原因，这样做是个坏主意。

在 OSX 上有一个快速修复此问题的方法。您只需要运行以下命令：

sudo chown -R `whoami` /usr/local/lib/node_modules
sudo chown -R `whoami` ~/.npm

Answer 2

这似乎是你/usr/local/lib/node_modules的权限有问题

所以你可以试试这个命令： sudo npm install --unsafe-perm -g expo-cli
