-ERROR: Failed building wheel for brotlipy"
-
-This indicate,you may need to install the windows compiler tools from $url so pip can compile all needed components
-If you follow the link it gives you https://visualstudio.microsoft.com/visual-cpp-build-tools/ you should be able to download the compiler for free.
-Basically, the python "wheel" here in the package for brotlipy contains a c library and they haven't provided a pre-compiled one for your specific platform, so pip is trying to do that for you so the library will work, but it wasn't able to because it couldn't find the appropriate compiler.
-If you already have a C/C++ compiler, you can probably tell pip to use that one, but since the microsoft compiler is free and available at the link, that's probably the easiest way to solve the error.
+If you get an error while installing brotlipy on Windows, installing the
+compiler above should fix it.
