Unable to follow instructions in the README file to get the project running

[stevenkore]

Ubuntu 18.04 clean install. Installed tasksel and via that LAMP stack (just to get PHP for other projects). Then installed yarn as per official documentation and installed vue cli with yarn. Then cloned this project and tried the instructions in the README file. Got these errors:

www-data@ubuntu:~/html/vue-realworld-example-app$ yarn serve
yarn run v1.17.3
$ BABEL_ENV=dev vue-cli-service serve
/bin/sh: 1: vue-cli-service: not found
error Command failed with exit code 127.

Adding export PATH="$(yarn global bin):$PATH" to ~/.bash_profile as some have suggested did not help.

What else to try?

@stevenkore Did your yarn install complete successfully?
