Question

在安装CVXPY时遇到以下问题，我也下载了Visual Studio的最新版本，但似乎也无法正常工作。

Answer 1

我遇到了同样的问题。我必须创建一个新环境并进行安装才能正常工作。转到Anaconda Prompt，然后执行：

conda create your_env_name
conda activate your_env_name
conda install -c conda-forge cvxpy
conda install spyder

我在工作中使用Spyder。我必须像在步骤4中那样在新环境中安装Spyder。找不到可以使用现有Spyder在两种环境下工作的解决方法。

错误：无法为使用PEP 517且无法直接安装的cvxpy构建轮子
