Getting errors while installing example-extension dependencies

[jasham]

Hello Jakubsta,

I am in middle of my project where I have to create chrome-extension.

Basically that chrome extension will takes data from block-chain and display in chrome content-script also when user click on that data one transaction happen which will increase the count in block-chain.
It will be a great help from your side if you solve my issue with installation of dependencies of this project.

Below are the error I am getting when I run npm instal; npm start

Hi @jasham
Did you try yarn install --pure-lockfile? I've tested it with node v9.3.0 and yarn v1.6.0.
