Because NPM servers in foreign countries, the use of NPM installation is relatively slow. Thus, the mirror can be used instead to provide Taobao NPM.
Global installed CNPM ( Company npm ):
# npm install cnpm -g --registry=https://r.npm.taobao.org
After the installation is complete, the command line prompt:
/opt/node-v12.14.1-linux-x64/bin/cnpm -> /opt/node-v12.14.1-linux-x64/lib/node_modules/cnpm/bin/cnpm
+ [email protected]
added 686 packages from 944 contributors in 178.301s
Now, you can use cnpminstead of npmcommand.
