Powershell: Travis CI macOS Builds are failing

[markekraus]

It appears something has changed, possibly external, and all of the macOS builds are failing (including nightly)

Also, the nightly badge for Travis CI macOS reports success when it clearly failed.

I'm looking into this. The badge caching is also still an issue.

Hello,

How did you fix this? Our project has same issue.

@benapetr Homebrew always uses the system Ruby, so it likely started with Ruby 2.0.0, installed the vendored Ruby 2.3.3, but then didn't use the vendored Ruby the first time.

In the interim and until this is specifically addressed by Homebrew or Travis CI, I fixed this by passing the no-auto-update flag:

HOMEBREW_NO_AUTO_UPDATE=1 brew install ...

[SteveL-MSFT]

@benapetr the main part of the fix was to move brew update earlier before using brew

oh, I tried this from your patch https://github.com/PowerShell/PowerShell/pull/5065 referenced in this thread, but maybe brew update would be better option: https://github.com/huggle/huggle3-qt-lx/commit/95267bbff361e11212519a609d8c832a704efb56
