    Hi,

    I'm having issues installing version 1.1.0

    ERROR: Could not find a version that satisfies the requirement solace-pubsubplus==1.1.0 (from versions: 0.2.0, 0.2.1)
    ERROR: No matching distribution found for solace-pubsubplus==1.1.0

    Here's the info:
    Platform: MacOs Sierra 10.12.6
    Homebrew version 2.4.9

    • installed python3.7

    • added a softlink
      ln -s /usr/local/Cellar/python@3.7/3.7.8_1/bin/python3.7 /usr/local/bin/python3.7
      python3.7 -V
      python 3.7.8

    • created and utilized a virtual environment
      python3.7 -m venv venv37
      source venv37/bin/activate

    • pip list versions under that virtualenv (venv37)
      pip==21.2.3
      setuptools==47.1.0

    • then pip install solace-pubsubplus==1.1.0
      The error above is showing. I used 3.7 per Readme guide

    Hey @Tamimi can you take a look and see if instructions need to be updated with the new version?

    Hi @marc , @Tamimi:

    I resolved the issue by updating my Mac platform to the latest BigSur. Originally my OS was 10.12, and looking at pypy downloaded files for 1.1.0, the filename for mac is stated 10_15. So I took a dive and upgrade my OS, and now I'm able to use 1.1.0

    Is it possible to include the package that supports for any platform? Thanks.

    Hey @ManuManu! Updating your pip pip install --upgrade pip should suffice 👍

    @argoran what platforms are you referring to?

  • argoran

    @Tamimi , Thanks for the reply. I am using a 10.14 Mac and for solace-pubsubplus, the available downloads for Mac requires that its version should be at least 10.15.

    I noticed in the previous version like for 0.2.1 the available download is for any platform. Is it possible to bring this back for 1.1.0 version?

    Also, regarding updating the pip. My pip version is already the latest but when I try to install solace-pubsubplus the only available versions are 0.2.0 and 0.2.1.

    Anyway, I am using docker as my work around for this.

    Hello @argoran , I am a product manager at Solace and I handle the APIs.

    I understand that 10.4 Mojave is still under support from Apple, however, it was released in 2018 and end of support is imminent from Apple. The rumor is Nov 2021 (so 2 months from now), which would be consistent with past MacOS releases being supported for 3 years.

    As such, Solace is unlikely to create a new package that supports MacOS prior to 10.15.
    Is it possible for you to upgrade to something more recent?

    Regards,
    Andrew

    I am having the same problem. Pip is updated, running in a venv, running latest MacOS etc etc and when I install I am offered only 0.2.0 or 0.2.1. I am working on an M1 mac if that makes any difference.

    Hi @Connor ! I tired the following and was able to install the latest version of the solace python API. Can you please confirm what version of python and pip you have in your virtual environment? See below what I did from scratch.

    # Create a new directory and navigate to it
> mkdir demo && cd "$_"

# Create virtual environment and activate it
> python3 -m venv venv
> source venv/bin/activate

    Thanks for your reply. Pip is updated to 22.04 and when I try install solace-pubsubplus I get this

    ERROR: Could not find a version that satisfies the requirement solace-pubsubplus==1.3.0 (from versions: 0.2.0, 0.2.1)

    ERROR: No matching distribution found for solace-pubsubplus==1.3.0

    My colleagues on Intel Macs do not have this issue, so I suspect it has something to do with the architecture. Any help/ideas would be much appreciated.

    Hey @Connor - I just confirmed that the supported operating systems listed on the PyPi project page do not have ARM support (yet) so you wont be able to use the Python API for now on your M1 MacOS natively. Alternatively, you can take a dockerized approach to using the API in a supported OS.

    Thank you for the information. Correct me if I am wrong, but there is no ARM-native pubsub+ image and I could not get the x86 image to run under emulation, so docker is not an alternative option unfortunately. Based on this:

    https://solace.community/discussion/1291/solace-pubsub-standard-docker-image-for-m1-mac

    It seems that I am not the only one encountering issues with running the docker images on M1. Thanks for all your help @Tamimi!

    Hi @Connor,

    You're correct - there is not an ARM-native pubsub+ event broker image at this time. Right now the easiest option, in most cases, for those using ARM based machines would be to run a broker in Solace Cloud.

  • Tamimi

    @Connor You are correct! So you wont be able to run the software Solace PubSub+ Broker image on docker on an ARM based M1 MacBook (Yet). However since you were wondering about using the Solace PubSub+ Messaging API, you can still run [the API] on a docker image and connect it to a cloud based broker.

    Say you have a local centos docker image docker pull centos (note that you can also have any python image) then run the image under emulation

    docker run -it --shm-size 1g --platform linux/amd64 centos:latest bash

    And then you can install and use the Solace API

    mkdir ./venv
python3 -m venv ./venv
source ./venv/bin/activate
python -m pip install --upgrade pip
python -m pip install solace-pubsubplus

    Note: Assuming you have python installed in your centos image:

    yum update -y
yum install -y python3

    Let me know if this helps!
