Install with pip not working with Alpine Linux

[robertonscjr]

When I try to install the rusty-rlp library on an Alpine Linux, the following error happens:

~ # pip3.7 install rusty-rlp
ERROR: Could not find a version that satisfies the requirement rusty-rlp (from versions: none)
ERROR: No matching distribution found for rusty-rlp

I need it to install web3py and pip workflow hangs exactly on this lib. Is there any way to install it manually?

Thanks!!!!

Olá Roberto! That's unfortunate. Am I right to assume tha you are on a 32 bit system? Or maybe you are on a 64 bit system but your Python is for a 32 bit system as it was the case in this issue?

Unfortunately, we are only able to provide 64 bit binaries right now. But I think it should be possible to fallback to a slower implementation for non 64 bit systems. I will look into that on Monday.

Can you run python -c 'import sys;print("%x" % sys.maxsize, sys.maxsize > 2**32)' and give me the output. (https://stackoverflow.com/questions/1405913/how-do-i-determine-if-my-python-shell-is-executing-in-32bit-or-64bit)

I have the same issue. I have windows 64-bit
here is the command I typed:

pip install rusty-rlp

I get the following error message:

ERROR: Could not find a version that satisfies the requirement rusty-rlp (from versions: none)
ERROR: No matching distribution found for rusty-rlp

when I run the command you posted

print("%x" % sys.maxsize, sys.maxsize > 2**32)

I get the following:

7fffffff False

Edit: It seems my Windows is 64 bits, but my Python is 32 bits. I will try to uninstall 32 bit python and reinstall 64 bit Python
Thanks

Yep, that's it. That worked for this user, too

[robertonscjr]

Hello @cburgdorf , thanks a lot for the answer!

When I ran the python -c 'import sys;print("%x" % sys.maxsize, sys.maxsize > 2**32)', the output was that: 7fffffffffffffff True. If I understand correctly, the output indicates that my Python is 64bit, correct?

Maybe it's something in Alpine. Because I tested the installation with the python:3.7 (Ubuntu) and it worked.

[cburgdorf]

@robertonscjr yes, looks like you are on a 64 bit system but there are problems with support for Alpine. I found a related issue in the maturin issue tracker: PyO3/maturin#154
That's the build system that we are using to create Python packages. I just skimmed over it so I'm not yet sure how it can be resolved.

On another windows, I got this.

[cburgdorf]

This indicates you have Python 32 bit installed on a win64 bit system.

No, I'm quite sure it's Python 64-bit and win64.
I solved this problem again.
It's because of the version of Python. Not available at 3.9, It must be <=3.8

[cburgdorf]

Ah, good catch! Supporting Python 3.9 should be as easy as adding it here (and then cutting a new release)
