Install Failure: ValueError, "insecure string pickle"

[raineorshine]

I am trying to install the Mix IDE but am getting an error when I try to install via brew. It fails at the qt5 make step. Running OSX 10.11.4.

$ brew install cpp-ethereum --with-gui

Excerpt from /Users/raine/Library/Logs/Homebrew/qt5/02.make:

This description of the error does not offer much that I can apply to this situation.

I have even fully uninstalled homebrew and re-installed it, same problem. Could anyone offer some help?

Hey. Are you the same person as "metaraine" from ...

Same issue? Same machine?

[raineorshine]

Yes. Same machine, same face :P. On Fri, May 6, 2016 at 3:40 PM Bob Summerwill notifications@github.com wrote:

Did you try nuking your whole Homebrew setup? Uninstall that as a whole, and reinstall Homebrew, then packages?

[raineorshine]

Yes, as mentioned in the ticket, I uninstalled all of Homebrew and re-installed. Same issue. On Fri, May 6, 2016 at 4:11 PM Bob Summerwill notifications@github.com wrote:

OK - so I think you next step needs to be logging a ticket on https://github.com/Homebrew/homebrew with regard to that Qt5 formula, asking for their help. If they don't have bright ideas (though they probably will - they are very savvy!) then you might need to talk to the Qt5 team.

Good luck! Sorry that you are hitting such a weird and unique issue :-(

Another option is trying the DMG (which is for Yosemite but might work on El Capitan too): https://github.com/ethereum/webthree-umbrella/releases/download/v1.2.4/cpp-ethereum-v1.2.4.dmg

I'm working on finishing up El Capitan automation at the moment. There is also a known issue where that DMG seems to contain an older version of Mix, but it does not. On Yosemite at least :-(

Thank you! I didn't know I could just try the Yosemite DMG. It installed and I was able to create a new project, so good so far!
