Question

我正在安装Psycopg2的连接器，但无法安装，如何成功安装？

使用此命令行进行安装：

pip install psycopg2

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>).

请尝试安装psycopg2-binary软件包而不是psycopg2。

pip安装psycopg2-binary

对于Windows以外的其他平台，您可以参考以下讨论。 How to install psycopg2 with "pip" on Python?
