Showcase the error

[jesstelford]

note: see the bug report here: CircleCI-Public/circleci-cli#151

This version of the code will run fine on circleci.com.

But when run locally on a non-Linux machine (eg; OSX), it will produce errors:

# creates the `node_modules` directory which is incorrectly copied to the docker image
yarn

# run the local circleci command
circleci local execute --job build

Gives the following output

❯ circleci local execute --job build

However, if you remove node_modules, everything runs fine:

# clean up files that aren't meant to be copied to the docker image
rm -rf node_modules

# run the local circleci command
circleci local execute --job build

Gives the following output

❯ circleci local execute --job build
