`lighthouse` binaries not in $PATH after installation

[dandv]

Do you want to request a feature or report a bug?

Bug/incompatibility with npm. Possibly related to #630.

What is the current behavior?

➜  ~ sudo yarn global add lighthouse
[sudo] password for dandv: 
yarn global v0.16.1

➜  ~ lighthouse
zsh: command not found: lighthouse

What is the expected behavior?

npm installs the binaries correctly:

➜  ~ sudo npm install -g lighthouse
[sudo] password for dandv:

I confirmed this is an issue with 0.19.1. According to the docs, the binaries should land in the directory returned by yarn global bin. When I run that as a command as a normal user, the result is /usr/local/bin. However, the directory that yarn global add actually installed the binaries into was:

  ~/.config/yarn/global/node_modules/.bin/

In this case, I think the bug is that yarn global bin is returning the wrong directory. Normal users don't have access to /usr/local/bin so wouldn't have installed global modules there. On the other hand ~/.config/yarn/global/node_modules/.bin/ clearly has "global" in the file name and is a per-user directory that can be relied up to be installed into.
