Installation fails due to conflicting rlp version

[NeolithEra]

Hi, users are unable to run Django-web3-auth due to dependency conflict with rlp package. As shown in the following full dependency graph of Django-web3-auth, Django-web3-auth requires rlp==0.6.0，while ethereum>=2.3.1 requires rlp<2.0.0,>=1.0.1.

According to pip’s “first found wins” installation strategy, rlp 0.6.0 is the actually installed version. However, rlp 0.6.0 does not satisfy rlp<2.0.0,>=1.0.1.

Thanks for your help.

Solution

1. Loosen the version range of rlp to be >=0.6.0.
2. Remove your direct dependency rlp, and use the rlp transitively introduced by ethereum.
3. Ask your direct dependency ethereum to loosen the version range of rlp to be ==0.6.0.

this commit appears to address the rpl version issue sanosano@15eb31c
has this worked for anyone? @sanosano @Bearle ?

Are there any suggestions for making this work with zulip? Should we use an old version of zulip?
