Question

尝试将 pip install recordclass (0.14.3) 模块安装到我的 pypy3 (PyPy 7.3.4-alpha0 with GCC 7.3.1 20180303 (Red Hat 7.3.1-5)) virtualenv 但遇到问题。有没有办法安装这个？还是该库目前不支持pypy？

错误的小片段是：

我打开了一个问题 https://foss.heptapod.net/pypy/pypy/-/issues/3438。但是，如果提高性能是您的目标，那么记录类可能是 PyPy 的错误工具。它使用（无限制）C-API，这在 PyPy 上很慢。您可能最好使用命名元组。

Pypy3 pip 安装记录类
