Python Setup.py Bdist_wheel Error: Microsoft Visual C++ Required

The error message indicates that Microsoft Visual C++ 14.0 or greater is required to build the wheel for 'greenlet'. This is a common issue when building Python packages that depend on C/C++ extensions. Here's how to fix it:

1. Install Microsoft Visual C++ Build Tools:

   • Follow the instructions on the link provided in the error message: https://visualstudio.microsoft.com/visual-cpp-build-tools/
   • Ensure you select the 'C++ build tools' component during the installation.

2. Retry the Command:

   • Once the Visual C++ Build Tools are installed, try running the python setup.py bdist_wheel command again.

3. Install from a Pre-built Binary:

   • If the previous steps fail, you can install 'greenlet' from a pre-built binary using: pip install greenlet-binary

Explanation:

Python packages that include C/C++ code often require a compiler to build their extensions. This error arises because the necessary compiler (Microsoft Visual C++) is missing. Installing the Visual C++ Build Tools provides the required compiler and other tools. If you still face issues, installing from a pre-built binary avoids the need for compiling the package locally.

Note: If you're encountering this error with other packages besides 'greenlet', the same solution applies. Install the Microsoft Visual C++ Build Tools, retry the command, or consider using pre-built binaries for those packages.
