【Mac環境】安裝psycopg2模塊時報錯收集

問題1：下載源碼解壓後使用python setup.py install返回錯誤：

python setup.py install
running install
running bdist_egg
running egg_info
writing psycopg2.egg-info/PKG-INFO
writing dependency_links to psycopg2.egg-info/dependency_links.txt
writing top-level names to psycopg2.egg-info/top_level.txt

Error: pg_config executable not found.

pg_config is required to build psycopg2 from source.  Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.

If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.

For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

按網上解決方案首先需要先安裝postgresql，運行命令：

brew install postgresql

安裝完成後再次執行命令，則報錯：

python setup.py install

ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'gcc' failed with exit status 1
