无法在 pycharm 中安装 cvxpy

Question

所以我尝试在 pycharm 中安装 cvxpy 包，但出现以下错误：

WARNING: You are using pip version 20.2.3; however, version 21.1.1 is available.
You should consider upgrading via the 'D:\Programmi (x86)\pythonprojects\Scripts\python.exe -m pip install --upgrade pip' command.

此外，给我的建议解决方案如下：尝试从系统终端运行此命令。确保为位于 'D:\Programmi (x86)\pythonprojects\Scripts\python.exe'.

的 Python 解释器安装的 'pip' 版本正确

你知道如何解决这个问题吗？我认为如果我尝试安装其他库也可能会出现此错误。

Answer 1

如 cvxpy' install 部分所述，在使用 pip install 之前，您需要安装 'Visual Studio build tools for Python 3'。

这正是您得到的错误：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/
