Installation fails due to conflicting grpcio version

[NeolithEra]

Hi, users are unable to run Chaosplatform due to dependency conflict with grpcio package. As shown in the following full dependency graph of Chaosplatform, Chaosplatform requires grpcio>=1.17.1，while chaosplatform-grpc>=0.1.0 requires grpcio==1.17.1.

According to pip’s “first found wins” installation strategy, grpcio 1.29.0 is the actually installed version. However, grpcio 1.29.0 does not satisfy grpcio==1.17.1.

Thanks for your help. Best, Neolith

Solution

1. Loosen the version range of grpcio to be <=1.17.1.
2. Remove your direct dependency grpcio, and use the grpcio transitively introduced by chaosplatform-grpc.
3. Ask your direct dependency chaosplatform-grpc to loosen the version range of grpcio to be >=1.17.1. @Lawouach Which solution do you prefer, 1 ,2 or 3? Please let me know your choice. May I pull a request to solve this issue?

@russmiles,Could you help me review this issue? Thx :p

[Lawouach]

Hello @NeolithEra, as we were saying elsewhere. Unfortunately, the whole chaosplatform has been discontinued. It's OSS so feel free to work on it of course but these repositories will move to the chaostoolkit-attic org at some point I'm afraid.

I'm very sorry if this is disapointing news.
