Trouble installing psycopg2 on Mac
问题
我对开发还很新，并且在尝试在Heroku上部署我的Django项目时遇到了一些错误。我正在尝试使用pip下载django-heroku包，但一直遇到以下错误：
ld: warning: directory not found for option '-L/usr/local/opt/openssl/lib'
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for psycopg2
Failed to build psycopg2
ERROR: Could not build wheels for psycopg2, which is required to install pyproject.toml-based projects
我尝试了很多方法，用尽了chatGBT，阅读了很多文章。我尝试重新安装了openssl并使用了以下命令：
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
我还尝试安装了psycopg2-binary，这个方法有效，但后来发现安装django-heroku需要psycopg2。我尝试了安装没有依赖项的django-heroku，但仍然需要psycopg2。
我尝试了升级Homebrew、pip、pip设置等等。所有关于这个问题的文章都比较旧了，所以希望能有一些新的见解！我使用的是macOS Ventura 13.4.1。提前感谢您的帮助！

I've tried so many things, exhausted chatGBT, and have read so many articles. I've tried reinstalling openssl and using these commands:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
I've also tried installing psycopg2-binary which worked, only to find that installing django-heroku requires psycog2. I tried installing django-heroku with no dependencies, but it still requires pspycopg2.
I've tried upgrading home-brew, pip, the pip setup, and so much more. All the articles on this are pretty old so some fresh eyes would help! I'm using macOS Ventura 13.4.1. Thanks in advance!
