为什么我不能从终端安装 vpython？

Question

我尝试使用命令 'pip install vpython' 从终端安装 vpython，但它抛出了这个错误。我有 python 3.8.9 和 windows 7、32 位。我也试过安装其他库，比如numpy，我成功了。

  note: This error originates from a subprocess, and is likely not a problem with pip.

我尝试输入 PATH 并且还安装了 cargo，因为它给我带来了另一个错误。我希望使用 pip 从终端成功安装 vpython

Answer 1

您正在使用 python 32 位，您应该改用 64 位。卸载 32 位版本并安装 64 位。我相信你的问题会得到解决。
