无法使用 pip3 安装合同

Question

我正在尝试学习如何在 python 中构建智能合约，但是当我尝试从终端安装合约时，我收到此错误：

我正在尝试使用 Mongo DB。 我安装了几个版本的 Python，包括 3.6.0，但我之前并没有真正使用过 Python，也不知道我在做什么。 我在尝试解决此问题时收到了一些不同的消息，但这就是它现在显示的内容。

您尝试安装的 Contracting 模块要求机器上存在 c++ 编译器。

解决此问题有两种选择。

首先，从https://go.microsoft.com/fwlink/?LinkId=691126安装 Visual C++ 构建工具并使用默认选项。

或者 - 按照 Lamden Consulting 文档中的说明安装 WSL - 请参阅此处的文档： https://contracting.lamden.io/windows
