Problems instally pgcli from source

Description

I was reading the tutorial, trying to installing pgcli from the source code.

During the pip installation (pip install -e .), I received the following error:

ld: library not found for -lssl

clang: error: linker command failed with exit code 1 (use -v to see invocation)

error: command 'cc' failed with exit status 1

After googling a bit, I found this StackOverflow question. I tried most of the answers (openssl and xcode were installed and updated), but this answer turns out to solve the problem.

I’m reporting this because I’m not sure this is a known problem (or if it’s a problem after all).

Your environment

• I’m using macOS, version 10.14.4
• I’m using Terminal, version 2.9.4 (421.1.1)
• Output of pip freeze command.

@hayd We discussed switching to binary / source in a few issues:

https://github.com/dbcli/pgcli/issues/844 https://github.com/dbcli/pgcli/issues/849 https://github.com/dbcli/pgcli/issues/974 https://github.com/dbcli/pgcli/issues/1036

This is beyond me why (there’s a huge discussion here but I still think they should have kept one package and let --binary-only and --no-binary flags do the work), but the psycopg2 documentation still states:

If you are the maintainer of a published package depending on psycopg2 you shouldn’t use psycopg2-binary as a module dependency. For production use you are advised to use the source distribution.

Ugh, ugh and ugh. We have so many people experiencing issues with the source package. I wish we could have a way for users to choose either psycopg2 or psycopg2-binary, but there’s no such way with pip.

It is possible to install and use pgcli with psycopg2-binary if you do this:

pip install pgcli
pip uninstall psycopg2
pip install psycopg2-binary

Unfortunarely, this workaround will only work if you are able to install psycopg2.

I’m going to create a branch switching pgcli to psycopg3. Maybe this will help us leave the binary/source mess behind.

This should be solved with psycopg 2.9 (https://github.com/psycopg/psycopg2/issues/1200)
