在AWS EBS部署Django应用时遭遇pg_config可执行文件未找到错误

我知道这个问题很常见，试过多种解决方案都没奏效，目前正在部署Django应用到AWS EBS。

eb-engine.log 错误详情 #

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.
