I am working with python 3.8.6 but for some reason it cant build a wheel for netifaces

error:

The relevant line is this:

Complete output (5 lines): 
running install running build running build_ext building 'netifaces' extension error: Microsoft Visual C++ 14.0 is required. 
Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

It is telling you that to complete the install you need to go get the tools it mentions and install them. The package is trying to run a compile during install and it needs those tools

  • Is there any way to avoid running a compile while installing ? It many cases it is absolutely not appropriate to run a compile (ie: install a compiler, system dependencies and so on) when installing a packages. I used to rely on pip --prefer-binary for that, but for some reason that doesn't work any more with netifaces. – kriss Mar 16 '21 at 13:54
  • There is a precompiled version of netifaces available. check here: https://www.lfd.uci.edu/~gohlke/pythonlibs/ for the package. you should be able to install it directly from the downloaded package. – LhasaDad Mar 18 '21 at 00:39

    Thanks for the link. Actually I could even do that myself (compile binary package on another machine, copy it on the target machine and install it). But I still believe pip should do the job and the precompiled versions should be available on pypi. Compiling a package may be right for a developer but looks unfit for deploiement. – kriss Mar 18 '21 at 16:07
  • I don't disagree, I prefer packages (when possible) that only have python content and do not need to ship what would be an opaque binary. – LhasaDad Mar 18 '21 at 23:27
