当我尝试ujson在 Windows 10 上的 python 3.6 中安装包时（安装 binance-python 库所需的）我收到此错误：

我该如何解决这个问题？

尝试在此处安装 Visual Studio：https ://visualstudio.microsoft.com/ 。通常，包依赖于 Visual Studio 的 C/C++ 编译器。

它似乎终止，因为运行以下命令：

error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.28.29333\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2

失败的。安装 Visual Studio 应该可以解决这个问题。
