这个python包，是需要rust来扩展编译的

安装rust后紧接着报错

How do I setup rust toolchain for orjson python library build in an alpine docker image?

提示输入命令

输入两条命令

rustup toolchain add nightly
rustup default nightly

切换nightly后

原本报错的地方没再报错，但后面又出现了新的错误

Running maturin pep517 build-wheel -i python --manylinux=off --strip=on
Error: Command '['maturin', 'pep517', 'build-wheel', '-i', 'python', '--manylinux=off', '--strip=on']' returned non-zero exit status 1.

注意maturin

PyPI的官方文档

pip install maturin

安装后依旧不行

手动执行该命令

虽然不想往这方面考虑，但我认为可能是python版本的问题。我现在用的是3.9.0。
现在尝试用3.8.5来试试

。。。

别用Beta版本
