Because of the domestic network environment, when downloading npm packages, we often encounter situations where they cannot be downloaded normally. Domestic Taobao launched the npm mirror, which is a complete npmjs.org mirror. The synchronization frequency is 15 minutes to ensure synchronization with the official service. It is recommended to use this image. The method of use is as follows:
Enter the following command to switch to Taobao mirror source:
npm install -g cnpm --registry=http://registry.npm.taobao.org
All the npm commands used afterwards can be replaced by cnpm for installation.
