Doesn't appear to work with yarn

[JustinBeckwith]

Trying to use yarn in 3-binary-data. Installed deps with yarn, and then ran gcloud app deploy:

beckwith-macbookpro:3-binary-data beckwith$ gcloud app deploy -q

I've been able to reproduce the error you encountered.

Both npm version 3.10.10 and yarn version 0.19.1 install jade version 1.11.0, which needs uglify-js version ^2.4.19. However, npm install correctly installs uglify-js 2.7.5 that satisfies the requirement for jade, but yarn install only installs uglify-js 2.2.5 that doesn't satsify ^2.4.19. Based on this, it looks like this could be a bug in yarn itself.

I'm going to see if I can fix this in the repo, but the tutorial has been updated to include instructions about Yarn, including deleting the yarn.lock to cause deployment to fall back to npm install.

The newest release of Google Cloud SDK (version 144.0.0) addresses this issue. I have confirmed that the 3-binary-data example can be deployed with yarn and deploys with npm if yarn.lock is specified in the skip_files section of app.yaml.

Closing this issue as it seems to be resolved. @JustinBeckwith feel free to reopen if this is not the case. Thanks!
