Since "yarn install" command took 40 seconds to execute I believe it did install dependencies silently. You may run "yarn --verbose" to make it more chatty.
Also you have node dependencies and they require certain version of node. On ubuntu image we have several versions of NodeJS preinstalled with NVM Node Version Manager (https://github.com/creationix/nvm). Please run "nvm use 6" to pick appropriate version of node before running "yarn" command.
