pip install web3 - 错误：需要 Microsoft Visual C++ 14.0 或更高版本

Question

我收到一条错误消息，类似于网站上已有的一些问题。 不幸的是，到目前为止所描述的解决方案都没有对我有用......

pip 安装 web3

不幸的是，如上所述，这里其他问题的可能解决方案到目前为止对我没有帮助（在这篇文章的末尾是我已经尝试过的简短列表）。 有谁知道任何其他可能的解决方案？ 如果需要，我还可以发布更多消息。 不幸的是，我对这个问题了解不多，无法缩小范围。

• 我还安装了 Visual Studio Build Tools 2019（现在可能有太多的单个组件，但我好几天都没有得到任何东西，我有点绝望......）：

Answer 1

我只是花了几个小时试图解决这个问题，最后我安装了 web3。 转到 Visual Studio 安装程序。 如果您已经安装了 Visual Studio 构建工具 2019，请单击修改，然后转到工作负载并使用 C++ 安装桌面开发。 如果您没有visiual studio build tools 2019，那么只需使用c ++进行桌面开发即可安装它。 我希望这对你有用！
