@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.
