  ERROR: Failed building wheel for lru-dict

Initially, the error said to install Visual C++ Build Tools > 14.0. I did install that. But now the error is above. I tried a few of the solutions mentioned in other forums but nothing worked.

Answer 1

This is old and it doesn't show if the issue was resolved. However, experiencing a similar issue I bumped into your question. This was resolved by following the instructions on installing VC Build Tools using the following command...

vs_buildtools.exe --norestart --passive --downloadThenInstall --includeRecommended --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Workload.VCTools --add Microsoft.VisualStudio.Workload.MSBuildTools
