Hi. I have downloaded the example-provider and example-consumer. Both of them are failing at npm install. Did anyone encounter this issue?

can you provide more info, there an many numbers of reasons an npm install may fail… what node version, what os, what actual error message

sure. I am running this on Mac OS, M3 chip. Node version is v18.20.3. The following is the errors I am getting on npm i

npm install

no that is weird and unexpected, however you can resolved by updating the pact dep to v12 or later which have pre built bindings rather than the user requiring to build on their machine https://github.com/pact-foundation/pact-js/blob/master/docs/troubleshooting.md#installation-failing-missing-python-c-or-build-tools

let me see if the --ignore-scripts works

it wont for v10/v11 as it wont trigger the node gyp build step with that set :(

the install worked with ignore scripts. For both consumer and provider. However, the consumer is not communicating with the provider. Might be a port issue.

great stuff Andrea, no problem
