Installation fails due to conflicting simplejson version

[NeolithEra]

Hi, users are unable to run Chaosplatform-auth due to dependency conflict with simplejson package. As shown in the following full dependency graph of Chaosplatform-auth, Chaosplatform-auth requires simplejson >=3.15.0，while chaosplatform-grpc>=0.1.0 requires simplejson ==3.15.0.

According to pip’s “first found wins” installation strategy, simplejson 3.17.0 is the actually installed version. However, simplejson 3.17.0 does not satisfy simplejson ==3.15.0.

Solution

1. Loosen the version range of simplejson to be <=3.15.0.
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 >=3.15.0.
