我试图为教程安装postgres,但是pip给了我错误:
pip install psycopg
我得到一个错误:
Error: pg_config executable not found.
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'.
pg_config我的virtualenv 在哪里？如何配置？我正在使用virtualenv,因为我不想在系统范围内安装postgres.

pip install -e <folder>
相反，该包有一个pyproject.toml文件，该文件似乎与setup.py通常的条目非常相似。
谷歌搜索引导我进入PEP-518，它setup.py在基本原理部分给出了一些批评。但是，它没有明确说明setup.py应该避免使用 ，或者pyproject.toml完全取代setup.py.
是pyproject.toml用来代替的东西setup.py吗？或者一个包应该同时带有 apyproject.toml和 a setup.py？
如何安装pyproject.toml处于可编辑状态的项目？
我正在为我的一个讲座工作项目,我需要下载包psycopg2才能使用正在使用的postgresql数据库.不幸的是,当我尝试pip安装psycopg2时会弹出以下错误:

有谁知道为什么会这样？是因为Sierra没有支持某些套餐吗？提前致谢!
