在python中导入web3时出错

Question

我正在尝试执行；导入web3"；语句，并得到以下错误。

编辑：我使用的是Python 3.9.0a1和pip 21.3.1。

我试过在VSCode终端和windows命令提示符下都这样做。

>>> import web3

您没有提到版本号。https://stackoverflow.com/help/minimal-reproducible-example

我从conda-forge安装了这些，MacOS 12.0.1:上有3.9.7解释器

• 键入扩展插件4.0.1
• web3 5.26.0

然后import web3工作正常。
