Why Am I Getting the 'Microsoft Visual C 14.0 is Required' Error During PyAudio Installation on Windows?

Error: "Microsoft Visual C 14.0 is required" During PyAudio Installation on Windows

When attempting to install pyaudio on Windows, users may encounter the error: "error: Microsoft Visual C 14.0 is required." This error occurs because installing pyaudio requires Microsoft Visual C 14.0, also known as MSVC.

Solution:

To resolve this issue, follow these steps:

1. Determine your Python version: Execute the command python --version in a terminal or command prompt to check your Python version. This will help determine the appropriate MSVC redistributable package to download.
2. Download Microsoft Visual C 14.0 Redistributable: Navigate to the Microsoft website and download the MSVC redistributable package for your version of Windows.
3. Install MSVC Redistributable: Run the installer and follow the on-screen instructions to install the MSVC redistributable package.
4. Reinstall PyAudio: After successfully installing MSVC, you can now reinstall pyaudio using the following command:

python -m pip install PyAudio

5. Verify Installation: Once the installation is complete, import pyaudio in your Python script to verify if it's working properly.

Alternate Method (in case pip installation fails):

1. Download the PyAudio wheel file: Visit the PyAudio website and download the appropriate wheel file for your Python version and operating system (e.g., PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl).
2. Navigate to the downloaded file: Use the cd command in a terminal or command prompt to navigate to the directory where the wheel file is downloaded.
3. Install PyAudio using pip: Execute the following command to install PyAudio using the wheel file:

pip install path_to_wheel_file

For example, if your wheel file is located at ~/Downloads/PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl, the command would be:

pip install ~/Downloads/PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl
