CodePudding user response：

First make sure you are using the recommended version of nodejs, which is currently 16.13.1. For that you can use the n module :

// if you haven't istalled before 
sudo npm install n -g 
//to have the latest stable version
sudo n stable

Then delete all your preview installs with npm and start over. For expo-cli :

sudo npm uninstall --global expo-cli
sudo npm install --global expo-cli
