尝试在 PyCharm 上安装软件包时，我继续收到此错误。

【参考方案1】：

我有同样的问题。 当我尝试安装 rusty-rlp 包本身并从网上下载文件时，我意识到 32 位 python 安装没有选项（***或 zip 文件）。 我使用的是 64 位 Windows PC，但由于某种原因，我运行了 Python-32bit 版本，所以我安装了 Python38-64bit 并再次运行 Pip，web3 的问题就消失了。

试试吧，如果您需要更多信息，请告诉我！

【讨论】：

当我在安装了 Python 3.9 64 位的 Mac OS 中尝试 pip3 install web3 时遇到类似的错误。

【参考方案2】：

@viken 的回答是真的！但就我而言，我必须卸载 Python 3.9 并安装 Python 3.8.7 才能安装 rusty-rlp。
