问题
My npm version: 6.4.1 node: 10.14.1 Ionic: 4.7.0 Cordova: 8.1.2 (Basically all of them are of the latest version)
When I try to install an ionic sidemenu at a specific location, an error occurs as such:
npm WARN deprecated browserslist@2.11.3: Browserslist 2 could fail on
reading Browserslist >3.0 config used in other tools.
npm ERR! code Z_BUF_ERROR
npm ERR! errno -5
npm ERR! zlib: unexpected end of file
npm ERR! A complete log of this run can be found in:

12T00_54_51_838Z-debug.log
So I navigate to the log document and have a look on the end of the file:

I really have no idea what this means. So I try to type "npm install" and fix all the problems on the subfolder in which I create my sidemenu, and the same issue, as above, occurs. I hope that anyone can help me address this issue.
回答1:
This problem seems to be a DNS issue when connecting to npm registry.
Please check (https://status.npmjs.org/) first to see if all services are operational then clear your npm cache.
Force clean your npm cache by doing:
npm cache clean --force
