Install latest version on Raspberry Pi

[mizamae]

HEllo,

I am trying to install the latest channels version (3.0.5) into a Raspberry and I found the problem of the dependency to the cryptography >3.4 package. This package requires a rust toolchain to generate the wheel installable and the RaspPi does not support it.

My question is, what is the latest version of Channels that requires cryptography version below 3??

P.D.: this incompatibility with RaspPi is the only drawback I can now find in channels latest versions

I've managed to install rustup / rust on a raspberry pi 400 to build cryptography. Takes a while to build, but it works.

channels dont have cryptography as its requirement, so I'm not sure if this is the right place to ask. Anyway, you can specify lower version of cryptography which does not require Rust yet (ie. 3.3.2). Works for me with the latest channels version.

When I try to install channels it installs cryptography >=3.4.6... and it requires the rust thing ..

• that does not mean it's a direct requirements of channels. channels have its requirements, which have their requirements etc., so it's somewhere in the chain, not in channels themselves
• wherever the cryptography requirement comes from, it tries to install any version of cryptography, so it goes for the latest one. But it is not mandatory. I'm using latest version of channels and it installs successfully with a manually specified requirement cryptography==3.3.2 in my pyproject.toml (or requirements.txt or whatever you use for requirements) without trying to install the latest version.
