无法在Windows 10上npm安装web3

Question

我关注了此页面上的所有内容：

https://medium.com/@PrateeshNanada/steps-to-install-testrpc-in-windows-10-96989a6cd594

除了第5步，我的Node.js版本是8.10.0而不是8.10.2，我认为这没有太大区别。

我已经安装了VS 2017 Community Edition，Windows 10 SDK，OpenSSL，npm-gyp。 我已经运行命令npm install --global --production Windows-build-tools来安装所有最新的构建工具，但仍然出现此错误。 需要帮助。

在我看来，node-gyp重建在我的计算机上失败。 这是为什么？

您是否尝试在npm install --global --production windows-build-tools运行命令npm install --global --production windows-build-tools ？

我遇到了同样的问题，并且在Powershell中运行了命令。
