Problem with Cargo while installing pydantic-core

[socloseeee]

I've installed cargo and rust:

apk add rustc
apk add cargo

But every time I encounter the same problem when installing the pip package pydantic:

(venv) localhost:~/HamsterValor# pip install pydantic

I have no idea what to do. It would be very nice if someone could pay my attention to root of the problem or write a solution.

Try putting:

[http]
check-revoke = false

in ~/.cargo/config.toml

I did that, and then a different type of error appeared.

I mean, the issue is right there

error: package `regex-automata v0.4.7` cannot be built because it requires rustc 1.65 or newer, while the currently active rustc version is 1.60.0

Alpine 3.16 only has Rust version 1.60.0, most packages require at the bare minimum 1.65.0 nowadays though
