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?

Thank you

Solution 1

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

Solution 2

just install cython

pip install cython #in the same environment

Solution 3

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

[DUDANF]

It seems like you're using python3.7, can you try pip3 install ... instead of pip install ...

[carl walters]

hummm thank you for the suggestion I just gave "pip3 install web3" ago but it resulted in the same error unfortunately.

[carl walters]

If I use pip3 does this also mean I need to downgrade my python version to 3? I just took a look at github.com/ethereum/web3.py and it says it suppports Python 3.6+

[DUDANF]

no pip3 is for any Python3+ be it 3.5 or 3.7. Also, you have python3.7 installed so shouldn't be a problem.

[carl walters]

Thank you, I just gave it ago on python3.6 just in case 3.7 isnt working for web3. Would you happen to have any idear on how else I might fix the error?

[DUDANF]

Im having a look. You also don't need VS Code installed since my docker doesn't have VS code. Do you have docker?

[DUDANF]

Can you actually run the command as admin? In mac/linux sudo pip install web3

[DUDANF]

[FlyingTeller]

@daudnadeem pip already seems to be correctly pointing to the version associated with python 3.7, so no need to run pip3. OP is also obviously on windows, so sudo commands will not work. The github link you have posted is a) for a completely different lib, b) a different error and c) has 200 downvotes and probably rather useless to fix an error where a certain header cannot be found

[carl walters]

Thank you once again, ahh I see wont be using that respiratory so to make sure I understand are you saying it isnt somthing I can fix? Thanks

[carl walters]

Manged to get it working by install all of the VS packages thanks a lot!

[carl walters]

Thank you for the help, I just Modified visual studio and installed "Visual studio SDK" and Windows 10 SDK (10.0. 16299.0) however after restarting I am still getting the same error. Is their any other things from VS I should also try installing? Thanks

[FlyingTeller]

For me, io.h is located in C:\Program Files (x86)\Windows Kits\10\Include\10.0.16299.0\ucrt after installing the 10.0.16299.0 SDK, could you check if that folder exists for you as well?

[carl walters]

ohhh how intresting yes it does! below is the code inside the io.h #pragma once #define _INC_IO #include <corecrt_io.h>

[carl walters]

Manged to get it working by installing just able everything inside VS Thanks!

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review

[LeanMan]

This was not a bad answer and worked for me. I would suggest to add the version of the build tools that worked for you and maybe other details like you need a microsoft account in order to access the download and add a link to the download form or page.

[Gino Mempin]

...not really useful answer for people that need to use Windows.
