我该如何解决这个问题?
【问题讨论】:
math.h 如果我没记错的话是一个基本的头文件,所以你可能需要安装某种 C/C++ 开发工具链。我不知道你到底需要什么工具链。 【参考方案1】: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。
它似乎终止了,因为运行了以下命令:
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。安装 Visual Studio 应该可以解决这个问题。
【讨论】:
我之前安装了visual studio c++ v14+构建工具,但我帮不上忙 这是 Visual Studio 2019? 谢谢你,我再次使用 MVSC 构建工具重新安装了 Visual Studio c++ v14+,它解决了我的问题。以上是关于Python中的ujson包安装错误的主要内容,如果未能解决你的问题,请参考以下文章
