在Python中安装qmcpy

Question

我未能安装“Python3中的准蒙特卡罗框架”qmcpy

我用pip install qmcpy，conda install qmcpy试过了。 我还下载了tar.gz file from the project page并尝试手动安装。什么都没用

我得到了一个很长的错误输出（我甚至在这里删除了一些部分，因为它太大了）：

Building wheels for collected packages: qmcpy

如何安装此软件包

Answer 1

您应该尝试安装错误信息正在抱怨的微软C++构建工具。

Answer 2

如果您查看输出的最后一行，其中显示error:，您将看到问题及其解决方案：

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

它为您提供了下载所需文件的链接：

Microsoft C++ Build Tools

如果您转到该链接并单击下载按钮，然后运行安装程序，您最终满足了前提条件。 然后，您可以再次启动构建，并且此错误应该消失
