pip install web3 not installing

Question

any advice would be greatly appreciated. I have installed visual studio like it tells me in the error and I have also attempted to pip install this in a venv environment however its still not working I have included the full error message below.

The error message is a little long this is the last message it gives error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.23.28105\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2 as mentioned I have already installed visual studio so I do not understand I have looked into it being a env variable that I need to create to no avalie it sounds like theirs a missing folder by the looks of the error, if so how do I go about fixing this?

Answer 1

On Windows 10, I tried to install Microsoft Visual C++ Build Tools, but that didn't solve the problem. So I installed a Linux-based system instead, used it as dual boot, and it works.

Answer 2

Not sure if my problem was the same, but downloading Microsoft C++ build tools worked for me

Answer 3

just install cython

pip install cython #in the same environment

Answer 4

The issue here is

c:\users\carl-\appdata\local\programs\python\python37\include\pyconfig.h(59): fatal error C1083: Cannot open include file: 'io.h': No such file or directory

What pip is doing here is downloading the web3 source and trying to compile it using the compiler that came with your visual studio in C:\Program Files (x86)\Microsoft Visual Studio

It fails, because it cannot find headers which come bundled with the Windows SDK (see also this post) which you can install using the Visual Studio Installer. Simply select "Modify" and then "Individual Components" and install the "Windows 10 SDK". That should solve your problem
