Parity-ethereum: Brew update gives "Error: Empty installation"

[dfinzer]

I'm running:

• Parity version: 1.6.10
• Operating system: MacOS
• And installed: homebrew

When I attempt to upgrade to 1.7.8 via Homebrew, I get the following issue:

brew update && brew upgrade parity
Already up-to-date.
==> Upgrading 1 outdated package, with result:
paritytech/paritytech/parity 1.8.2
==> Upgrading paritytech/paritytech/parity --stable
==> Downloading http://d1h4xl4cr1h0mo.cloudfront.net/v1.7.8/x86_64-apple-darwin/parity

Error: Empty installation

Any ideas?

Hello. Let me assist you.
Try running separately

brew tap paritytech/paritytech & brew update

and later:

brew upgrade parity

Let us know if it did help.

Regards,
Julia.

Didn't work for me:

~ $ brew upgrade parity

Error: Empty installation

Yeah I'm still not able to get it to work either.

[testrain]

same error here.

You are on stable channel, try

brew install parity --beta

[dokterbob]

Thanks for the tip!

But that still doesn't fix the bug: brew install --upgrade should not result in an error condition.

Homebrew raises an "Empty installation" exception if it appeared that no significant files were included during install.

[dokterbob]

Yes and it tries to upgrade even though it should not; it goes off to try and install the beta version, which then it doesn't, yielding the exception.

Has this been solved? I am also having this issue..

[dokterbob]

Nope.

I can not reproduce this. Did you try removing and reinstalling Parity? What steps are required to reproduce this? Can you run brew with --verbose and share the log here?

[dokterbob]

It seems that, now, a clean install seems to work fine. Will report if subsequent updates fail again.

We did a minor logic change in the brew script which could have caused this; I do not necessarily see why though. Please let me know if this happens again.

[sbenario]

FWIW I'm also seeing the empty installation issue as well. Previously installed stable using homebrew, and now homebrew upgrade results in Empty installation.

Happy to try some other debugging steps to help figure out the issue.

Here's a layout of the file structure after attempting to do both a brew upgrade and a brew reinstall parity:

I'm clueless, how could this commit have caused this: https://github.com/paritytech/homebrew-paritytech/commit/a4002b07bd06b836d5759365d10519e2602e5e1c

It clearly contains bin/parity, ... Smells like a brew bug. Any ideas?

[Sjors]

uninstall and reinstall worked for me as well, maybe as a result of the recent fix.
