Docker Startup Error: AttributeError: module 'rlp' has no attribute 'Serializable'

[anoduck]

Literally followed the instructions for docker installation verbatim, and recieved the error: AttributeError: module 'rlp' has no attribute 'Serializable'. Attached to the tty, and ran the command pip3 install eth-ape[recommended-plugins] AND pip3 install -U eth-ape[recommended-plugins] everything came up installed both times. Looked for more documentation on performing a docker installation, and found the same information contained in the README.md. Kinda lost as to what to do now.

I will try to remember to return later and provide the full output.

This seems like some sort of dependency issue w/ py-rlp

Will look into it!

@anoduck Can you include OS information?

[anoduck]

@unparalleled-js host OS is Kali Linux, but running docker not as root, but as unprivileged "normal" user. So, basically same as Debian unstable.

Full command executed: docker run --volume $HOME/.ape:/root/.ape --volume $HOME/.vvm:/root/.vvm --volume $HOME/.solcx:/root/.solcx --volume $PWD:/root/project --workdir /root/project apeworx/ape compile

Full output of error that followed:

[fubuloubu]

are you using stable or latest docker tag? (or an older version)

[anoduck]

are you using stable or latest docker tag? (or an older version)

Using @latest, of course.

[fubuloubu]

are you using stable or latest docker tag? (or an older version)

Using @latest, of course.

Just for sanity check, can you try @stable?

No difference between running @latest & @stable. Both resulted in the same error.

I'm able to recreate the error on the latest docker image on ubuntu WSL2

[anoduck]

Just spouting off some observations, but it appears the error is located within the ethereum libraries and not within ape itself, particularly the eth-rlp package. So, it might be Ethereum's problem to fix.

The documentation that refers to the module creating the error can be found here: https://eth-rlp.readthedocs.io/en/latest/eth_rlp.html#eth_rlp.main.HashableRLP.from_bytes

[sabotagebeats]

After doing some research it seems the error is coming from this file:
https://github.com/ethereum/eth-rlp/blob/master/eth_rlp/main.py

that file imports this library also: https://github.com/ethereum/pyrlp
however I still haven't found where this breaking change occurs

I was able to try an older version of the ape docker image and it works to compile but the latest version does not.

[sabotagebeats]

with these changes to the dockerfile it seems to work. I'm exploring which of the changes it is specifically.

FROM ubuntu:22.04
RUN apt-get update && apt-get upgrade --yes && apt-get install git python3.10 python3-pip --yes
ADD . /code
WORKDIR /code

# need to use typing-extensions<4 to deal with issue 387 bug: Docker will not build
# TODO: Figure out a better solution or wait for it to resolve itself.
RUN pip install typing-extensions==3.10.0.2
RUN pip install .
RUN ape plugins install alchemy ens etherscan foundry hardhat infura ledger solidity template tokens trezor vyper
RUN pip install eth-rlp==0.3.0
ENTRYPOINT ["ape"]

[sabotagebeats]

each of the changes seem necessary for one reason or another to have it working.

[anoduck]

May be a little premature, but seeing there is a new docker image release, I am going to go ahead and pull @latest, and see if the issue has been taken care of. Fingers crossed.

Pulling is slower than frozen molasses.

[anoduck]

Well, another update to the latest image came through, and my pull request never completed before timing out. So, I am starting the pull request all over again, at a snail's pace. Wish ATT would finish setting up fiber, the cables have been out there for almost a month now.

[anoduck]

Yep, it works...now the fun begins...

[antazoey]

If encounter this issue RLP has not attribute 'Serializble' at any other point when using the Ape, the fix is:

pip uninstall rlp --yes && pip install rlp==3.0.0

I have encountered this issue outside of docker, like when installing other libs and such, and then I have to do this again. It is odd. The init.py file for rlp changes for some reason. Maybe a bug related to having multiple installed packages named rlp.

Thank you @unparalleled-js - came here with the same issue and this helped.
