Steps to reproduce

Try to use pactflow command provided by pact-cli package

[bahamut657]

Even installing the dependency statically in the package.json file the error persists. It seems related to the cwd used while calling standalone/darwin-arm64-2.4.6/pact/bin/pactflow

There are alpine specific dependencies required as the ruby runtime which the pact cli tools rely on is built against glibc not musl, please see the following wiki

hmm your repro mentions alpine linux, but your console commands are from macos 🤔

will get a fix out shortly, have identified the issue (we use the full path for the other binaries, and I hadn't used the correct full path variable for the pactflow binary)

Cheers for the report!
