尝试使用 Python 安装 Web3 时出错

Question

尝试使用 pip 安装命令在 Python 中安装 web3，它会运行 setup.py install for cytoolz 然后失败如下：

我搜索了许多建议使用 Visual Studio 构建工具安装 Microsoft Visual C++ 14.0 的文章，我已经这样做了。

我还从 C:\Program Files (x86)\Windows Kits\10\bin\x86 复制了 rc.exe 和 rc.dll 到 Z0D61F8370CAD1D4162F8370CAD1D4162F8370CAD1D412F8370CAD1D4162F8370CAD1D412F8370CAD1D412F8370CAD1D4162F8370CAD1D4162F8370CAD1D4162F8370CAD1D4162F8370CAD1D416 文件夹中的 rc.dll。

不幸的是，这些似乎都没有奏效。

我尝试自行安装 cytoolz，但它在下面给出了相同的错误。
