Question

我尝试为python安装cvxpy（https://www.cvxpy.org/install/）。我在所有项目中都使用Python 3.8，不喜欢在使用3.7的虚拟环境中使用。有人有在python 3.8上使用cvxpy的修复程序（我正在使用Windows）吗？

谢谢！

您的问题似乎不是Python版本，但缺少构建工具。安装Microsoft Visual Build Tools并确保它们位于PATH上（以便conda可以执行MSBuild.exe）。

从cvxpy（在pptx中）构建工具installation instructions。

无法使用python 3.8安装cvxpy
