yarn is having troubles with the network connection

Question

I tried to install a package with yarn earlier today and I got this

yarn install
yarn install v1.9.4
[1/4]          


        

Answer 1

Try clearing your cache

$ yarn cache clean
$ yarn // to install dependencies, no need for "yarn install"

Approach 2

$ yarn install --network-timeout 1000000
