Travis x86_64-apple-darwin11 errors: "Configuring boost... /bin/sh: 1: requires: not found" #11906

I'm seeing travis errors for the x86_64-apple-darwin11 build in two PRs (#9381, #9680). Failure happens reliably within a few minutes of restarting the build. Output:

The command "if [ -z "$NO_DEPENDS" ]; then make $MAKEJOBS -C depends HOST=$HOST $DEP_OPTS; fi" failed and exited with 2 during .

Your build has been stopped.

"requires" seems to be a part of an earlier error : https://travis-ci.org/bitcoin/bitcoin/jobs/316549754#L354

grep: requires: No such file or directory
grep: Node.js: No such file or directory
grep: 4.0: No such file or directory
grep: or: No such file or directory
grep: higher: No such file or directory
grep: to: No such file or directory
grep: be: No such file or directory
grep: installed.:: No such file or directory

The search term "requires Node.js 4.0 or higher to be installed" points to software called yarn, not sure if related.

Interesting, and that error on line 354 is very early on, it seems before our configuration environment variables are even loaded (line 381). RIght now, I'm trying rebasing on latest master c66adb286a89738a6a5218be2ecfea8e398878dd -> 8585bb8f058441b951b8012de8c0e45207528dec to see if that will maybe make travis clear some bad cache and work around the error.

Same problem's still happening after rebase:

As suggested by @MarcoFalke, I'm currently trying to run travis directly on my #9680 github branch:

https://travis-ci.org/ryanofsky/bitcoin/builds/316992931

This looks like it might be related to https://github.com/travis-ci/travis-build/pull/1275

Closing, since the issue apparently was caused on the travis end (upstream). Should be fixed now
