尝试在 PyCharm 上安装软件包时，我继续收到此错误.

I continue to get this error when trying to install the package on PyCharm.

推荐答案

我遇到了同样的问题.当我尝试安装 rusty-rlp 包本身并从 Web 下载文件时，我意识到 32 位 python 安装没有选项(wheel 或 zip 文件).我在 64 位 Windows PC 上，但由于某种原因，我运行了 Python-32 位版本，所以我安装了 Python38-64 位并再次运行 Pip，web3 的问题消失了.

I had the same issue. As I was trying to install the rusty-rlp package itself downloading the files from the web, I realized there is no option (wheel or zip file) for 32-bit python installations. I'm on a 64-bit windows PC but for some reason I had a Python-32bit version running so, I Installed Python38-64bit and runned Pip again and the issue with web3 disappeared.
