I installed version 12.18.3 before, and I kept reporting errors when I used npm. At first I thought that the port was occupied! A lot of Baidu! Say delete the two files node_modules and package-lock.json! Already the same! As a result, install the latest version 14.9.0 directly!
Inexplicably no problem! Maybe the version is down!
Commonly used installation modules
npm install mysql
npm install express
npm install https
npm install fs
