It seems this method was added only in Symfony 4.2 so I suspect you're running a lower version. Try upgrading symfony. In the meantime I'll whip up a PR to remove support for older versions.

We'll probably release Envoy 2.0 soon which will drop support for old versions. We're currently waiting a bit to see how symfony/symfony#32126 plays out before doing the release. In the meantime please use v1.6.1 for now.

Does Envoy use my local symfony components? Or global?

@peterpan666 depends if you've installed it locally or globally

It's installed globally, I thought Envoy does not work locally. Envoy is the only package I install globally on the CircleCI image, but I don't know if other packages are shipped with a basic CircleCI image though.

I use Envoy locally a lot myself

@peterpan666 can you confirm this was fixed if you update tot he latest 4.x version of symfony/process?

Hi Dries,

I can't test it right now 😕

I'll just fix the version of Envoy until 2.0 is released, I've got many projects to maintain and it's the better solution I've got right now.

Thanks for your help!
