我试图安装psycopg2-binary (pip3安装psycopg2-binary)在虚拟环境中我的Django项目在Centos 7预装Postgresql 12和有众所周知的错误:
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.
我试图安装python3-devel postgresql-libs postgresql-server postgresql-devel postgresql-contrib，但仍然有这个错误。
pip3 install psycopg2, PIP install psycopg2 -同样的问题
PS问题已经通过更新pip解决了(pip install—upgrade pip)。
你可以试试这个方法，非常有用
sudo apt-get install postgresql postgresql-dev python-dev
