pip3 install

[joaopmrod]

I get this error when trying to install on my odroid-xu4 (Ubuntu 18.04 LTS (GNU/Linux 4.14.37-135 armv7l, Python 3.6.5 (default, Apr 1 2018, 05:46:30) [GCC 7.3.0] on linux)

How can I fix it?

odroid@odroid:~/centopeia_firm$ pip3 install umodbus

Thanks for submitting this issue. At the moment I don't have much time to look into it. But a quick workaround for you would be downloading the source and then run python setup.py to install it manually.

Is there any update on this. This doesn't seem to be a problem on windows. It's happening to me after I've finished my development on windows and wanted to deploy the code on Linux. The error message is as below:

It seems that you are having network issues unrelated to uModbus.

I am running into this exact same issue building a Linux container image for docker. pip install works fine pip3 install fails with

Collecting umodbus

I believe this has something to do with the UTF-8 characters in the readme file and a bug in pip3.

@8minutenergy I cannot reproduce the bug. Could you post which docker images you used and which commands you issued?

[8minutenergy]

I am using ubuntu:cosmic. Work around is to run pip install umodbus instead of pip3 install umodbus.

Dockerfile

FROM ubuntu:cosmic

SHELL [ "bash", "-c" ]

RUN apt-get update && apt-get install -y tzdata && apt-get install -y \ build-essential \ python-dev \ python-setuptools \ openssl \ libssl-dev \ libevent-dev \ python-pip \ git \ gnupg \ dirmngr \ libyaml-dev \ openssh-client \ python3 \ python3-dev \ python3-venv \ python3-pip \ python3-setuptools \ python-numpy \ python-pandas \ && pip install PyYAML \ && pip install umodbus \ && pip3 install click \ && pip3 install voluptuous \ && pip3 install umodbus \ && rm -rf /var/lib/apt/lists/*

[OrangeTux]

Weird, It works on my machine.... I'll later investigate it later

[OrangeTux]

@8minutenergy Can you add this line to the Dockerfile:

FROM ubuntu:cosmic

ENV LANG C.UTF-8

        build-essential \
