Web3 Install is taking forever

[cherb-programs]

Hi Guys,

I'm having issues installing web3 with pip install web3. I've ran into the VS C++ tools error initially, but after installing everything the VS builder tools that went away. Now when I run pip install web3 It runs forever. It gives me this line constantly "INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime.", and "INFO: pip is looking at multiple versions of xxx to determine which version is compatible with other requirements. This could take a while.", where xxx is the package it is trying to install inside of the web3 package.

I'm not having much luck with this one, I've tried setting up a virtual environment, adding this to to system variables "C:\Users\user\AppData\Local\Programs\Python\Python310\Scripts". I've also tried different terminals such as git bash and powershell (I'm on windows 10). I'm not sure where to go from here.

Hi. I faced the same error. what you should do is this:

1-instead of python 3.10, you must install python 3.9 or maybe a lower version (3.9 worked for me)
2-remember to add the python, npm, pip and web3 path to system variables if you encountered the not recognized error.
3-It is caused by the latest version of pip . A temporary fix is to downgrade your pip version to 20.2:
pip install --upgrade pip==20.2

let me know if it fixed the problem, because it worked for me pretty good.

@KAD105 Ok so I managed to install web3 on my Raspberry Pi 4. Just copied my code over and will test tomorrow. I was able to install solcx but tried updating the version to 0.6.0 but got an error message. Will update tomorrow.

i can not down grade the pip =(..!! i fells so confusing to my

maybe i have downgrade from same path i had to upgrade it.

[Evancitoo]

it doesn't feel god downgrade the update fells counter intuitive. because i don understand at all i had to prove many combinatoric of stuff and try to understand some out put message

..

[Evancitoo]

now there should be a similar command to lower the python and dont make me uninstall and re install and reboot vs code. and wait until some error that not working any more.

[Evancitoo]

see..!! it tells me that i have to upgrade my pip again so i had to upgrade. but i tried upgrade but then web3 can not update or install correctly then

Hi guys, checking in, I've managed to get past this stage which I believe was a combination of a few errors in my environment. I still believe my environment isn't 100% right because I keep running into these weird package errors as I progress through the course (PIPX for example). Where it doesn't recognize the command even though it's been installed. Usually it's because it has installed itself somewhere weird and it's not on path (I installed like 4 different python versions trying to solve this and they're all in different places, so that will probably bite me in the ass down the track, but hey, it works!...for now). So I'll elaborate on what I did and hopefully this helps someone. I spent hours trying to figure this out...very frustrating indeed.

Firstly, KAD105's steps are definitely things to try if you run into similar errors.
Build tools are necessary so be sure to have them installed. I got mine from here https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019 then scrolled down and selected "Build Tools for Visual Studio 2019". I saw @ArcusConsulting was having problems with this link but it seemed to work for me. Maybe try using another browser, Chrome worked for me.

Once that's downloaded, restart your PC before continuing! Now, From what I read Python 3.10 and Pip weren't working correctly so definitely try using Python 3.9 or something lower and don't forget to change your interpreter to whatever Python path your using!!!

Now, I played around with different virtual environments, Anaconda and different shells. I used a combination of WSL, git bash and Powershell to get all the packages installed but I think if I were to do it again I would do the following.

Install VS build tools.

Install Python 3.9 or lower and ADD to PATH!!
You can check what's in your path in PowerShell but typing $env:Path. Ensure you've added "path/to/python/Python.exe ", "path/to/python/Python39/site-packages" and "path/to/python/Python39/Scripts" in to your System Variables (I put them in User Variables as well just to be safe lol). Also, close every terminal that you have open including the ones in VS Code before restarting VS Code. I had an instance where I ran a PowerShell outside of VS Code and it was recognizing that was recognizing PIPX and the one inside VS code wasn't. I didn't release I had 2 VS code windows open so when I restarted the one I was working on it still wasn't picking it up. It wasn't until I restarted BOTH of the VS Code Windows that it worked.

Run everything in Admin mode.

You may have to play around with py, python or python3 syntax to get a certain packages to work. Or install it through npm or another method if pip/pipx isn't playing ball. From there, make sure said package is added to PATH using the method above.

Anyway, hope that helps my fellow Windows users. Once I finish this course I will probably just make a dual boot system for Linux and just use that moving forward, does that seem like a good idea?

No problems, I've been caught out with that in the past too! Glad it worked for you.
