Unable to install via composer on OSX: you are running this with PHP and not HHVM

[abirchall]

See the following console output. Any ideas? hhvm docs appear to say the latest version of composer will auto-detect whether to run with php or hhvm, could that be broken?

Please update your composer installation as follow :

$ composer self-update

Issue : previously, we used hhvm to run composer ( hhvm $(which composer) require ... ), but recently, hhvm became unable to run composer as composer uses php references, a change was made to composer so that it executes hhvm --version to retrieve HHVM version and check it against composer.json instead of relying on HHVM_VERSION constant when its running under hhvm.

[ssandler]

It looks like his composer is already up to date? Perhaps you have php aliased/symlinked to point at hhvm?

If you do have it aliased you don't want to change that, you can also run it explicitly with php like /usr/bin/php /usr/local/bin/composer require facebook/xhp-lib

[azjezz]

i don't think that's the case.

1. composer won't start under hhvm
2. even if the check was removed, composer won't result in you are running this with PHP and not HHVM. under hhvm ( see : https://github.com/composer/composer/blob/79a300eaac89be9a4b05cd992930f343ba4f084d/src/Composer/DependencyResolver/Problem.php#L111 and https://github.com/composer/composer/blob/ff246e3e85cc972d3c66c3b66aa233415cc5ed89/src/Composer/DependencyResolver/Rule.php#L174 )

composer will sometimes say that if there are other unresolvable dependency issues. I'm not sure of the exact case.

That said, I can't reproduce this on a clean checkout.

• Could you paste your full composer.json and composer.lock?
• How did you install hhvm?
• Is this on an FB-managed machine?

[abirchall]

Thanks for the fast responses!

run it explicitly with php like /usr/bin/php /usr/local/bin/composer require facebook/xhp-lib

This results in the same behavior.

run composer self-update

It's already up to date:

abirchall-fb[abdev](master): composer self-update
You are already using composer version 1.9.2 (stable channel).

Could you paste your full composer.json and composer.lock?

The contents are in my first post; it's a clean composer.json (with no requirements yet) and there is no lock file yet as I've yet to install anything.

How did you install hhvm?

Using Homebrew: brew install hhvm. I also installed composer via Homebrew.

Is this on an FB-managed machine?

It's on my FB work laptop (MacBook).

[fredemmott]

• Is homebrew installing in it's default location - /usr/local/ - or somewhere else?
• what do which hhvm and which hh_single_compile say?
• does brew doctor report any problems?
• what's the output of hhvm --php -r 'echo HHVM_VERSION."\n";' ?

[fredemmott]

(FB chef doesn't like homebrew being in /usr/local, but HHVM's packages aren't relocatable)

[abirchall]

Is homebrew installing in it's default location - /usr/local/ - or somewhere else? what do which hhvm and which hh_single_compile say?

what's the output of hhvm --php -r 'echo HHVM_VERSION."\n";' ?

This may be a hint in the right direction...

abirchall-fb[abdev](master): hhvm --php -r 'echo HHVM_VERSION."\n";'

But if I use sudo, it's fine:

abirchall-fb[abdev](master): sudo hhvm --php -r 'echo HHVM_VERSION."\n";'
4.39.0

[abirchall]

Interesting, /Users/abirchall/.hhvm.hhbc was owned by root:

abirchall-fb[abdev](master): ls /Users/abirchall/.hhvm.hhbc
-rw-r--r--  1 root  1876110778  3694592 Jan 31 23:29 /Users/abirchall/.hhvm.hhbc

I removed it and it was re-generated (owned by my user) when I ran hhvm --php -r 'echo HHVM_VERSION."\n";':

abirchall-fb[abdev](master): ls /Users/abirchall/.hhvm.hhbc
-rw-r--r--  1 abirchall  1876110778  3694592 Jan 31 23:31 /Users/abirchall/.hhvm.hhbc

... and then after this composer worked:

abirchall-fb[abdev](master): composer require facebook/xhp-lib

Will leave this open in case there's anything we should do to try to catch and mitigate this.

[fredemmott]

Closing; this probably belong as an issue against facebook/hhvm to send a PR improving composer's error handling in this case, or an issue against composer itself. Composer is probably 'more correct', but more likely to be seen by the right people on facebook/hhvm
