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>).

错误：找不到pg_配置可执行文件。
从源代码构建psycopg2需要pg_配置。请添加目录
将pg_config包含到$PATH，或使用
选项：
python setup.py build_ext--pg config/path/to/pg_config build。。。
或者使用'setup.cfg'中的pg_config选项。
如果您希望避免从源代码构建psycopg2，请安装PyPI
改为“psycopg2二进制”包。
有关更多信息，请查看“doc/src/install.rst”文件（另请访问
).
