The Link in the error seems to be outdated. Try with the below link:   https://visualstudio.microsoft.com/visual-cpp-build-tools/   Step 1: It will install file and Visual studio will run and install 70 MB approx.  Step 2: The visual studio build tools will appear. Click on resume/Install.         Step 3: It will download and install 1.16 GB approx data. Wait for it to install.         Step 4: It will ask you for a reboot. So, go ahead and do it.        Step 5: Run your command again by which you were getting error. It should work.  For me it was coming while installing pyaudio:  So, my command will be :  python -m pip install pyaudio   while doing so I was getting one more error :   src/_portaudiomodule.c(29): fatal error C1083: Cannot open include file: 'portaudio.h': No such file or directory  So, for this error I tried below commands: (Run as administrator if it didn't work.)  pip install pipwin pipwin install pyaudio   Hope we were able to resolve the issue 😉 ...
