For the 3.9 release, it did not have wheels available until a while after the release.
In general as time goes on package maintainers are putting in more and more effort to shorten this window. In this case, psycopg2-binary added wheels for 3.11 on Oct. When you install a package, you can just download the binary wheel and don’t need to compile it (unless you’re using Alpine Linux, in which case wheels may or may not be available).īut at least for a short time after 3.11’s release, some packages won’t have wheels for Python 3.11 uploaded yet. Typically, Python package maintainers upload compiled versions of their packages–known as “wheels”–to PyPI. Please add the directoryĬontaining pg_config to the $PATH or specify the full executable path with the Pg_config is required to build psycopg2 from source. $ python3.11 -m pip install psycopg2-binary
When I tried to install it on Python 3.11 on the day of 3.11’s release, things don’t go well: To begin with, not all packages can be installed on 3.11 yet.įor example, psycopg2-binary provides bindings to the PostgreSQL database it had tens of million of downloads from PyPI over the last month. With that in mind, let’s consider the problems with using 3.11 immediately after a release, and in the following months: 1. In addition, because upgrades involve so many different groups, coordination and releases take even more time. None of this should be read as a complaint towards the people doing the maintenance, they’re doing hugely valuable work for free, and everything takes time. The problems with a new major Python releaseĪs with many open source projects, Python, Python libraries, and most of the toolchain and packages mentioned in this article are based on volunteer labor. To understand why, we need to consider Python packaging, the software development process, and take a look at the history of past releases. Now that it’s been out for longer, but you might still have issues, but upgrading is worth trying. Immediately after the release, you probably didn’t want to upgrade just yet. Python 3.11 is out now–but should you switch to it immediately?Īnd if you shouldn’t upgrade just yet, when should you?
