> This requirement was pinned as of PR 5036, as related to a breaking change
> with respect to the package namespace. This PR modifies which package to
> refer to - prior to 2.8 the package was a binary wheel, but with 2.8+ the
> appropriate installation package is {{psycopg2-binary}}
> h3. Explanation:
> [Full explanation
> here|http://initd.org/psycopg/articles/2018/02/08/psycopg-274-released/]
> For most of psycopg2's history, they had distributed pre-compiled binaries
> (or "wheels") which would get installed when you did {{pip install psycopg2}}
> (rather than compiling the source code upon installation). At some point
> psycopg2 found that there were some segfault issues that were appearing in
> the pre-compiled versions. Granted, this could be fixed if you installed by
> explicitly saying you wanted to compile from source rather than retrieve the
> binary version, but the psycopg2 devs felt that this would be better
> addressed by publishing a separate package that was the pre-compiled binary,
> while keeping the original package as compile-from-source only. The upshot of
> this is that everyone who was used to installing {{psycopg2}} and getting the
> pre-compiled binaries was now having to compile the package on install unless
> they moved over to {{psycopg2-binary}} instead. The packages are effectively
> the same, only the pre-compiled versions are usually more optimized, run
> quicker on the systems they're build for, and don't require compilation
> dependencies to install. So, in accordance with the warning provided by
> psycopg2 ({{UserWarning: The psycopg2 wheel package will be renamed from
> release 2.8; in order to keep installing from binary please use "pip install
> psycopg2-binary" instead.}}), I've swapping this over to psycopg2-binary.
> I've also confirmed that {{psycopg2-binary}} is available from {{2.7.4}}
> onwards:
> $ pip install psycopg2-binary== Collecting psycopg2-binary== ERROR: Could not
> find a version that satisfies the requirement psycopg2-binary== (from
> versions: 2.7.4, 2.7.5, 2.7.6, 2.7.6.1, 2.7.7, 2.8, 2.8.1, 2.8.2, 2.8.3,
> 2.8.4) ERROR: No matching distribution found {color:#d73a49}for{color}
> psycopg2-binary==
