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
<https://www.psycopg.org/docs/install.html>).

Answer 1

您可以安装预编译的二进制文件。有关更多信息，请参阅此Answer。

pip install psycopg2-binary

Answer 2

请按照说明进行操作：您可以添加目录，也可以使用以下选项指定完整路径。另一个解决方案是setup.cfg

要从源代码构建psycopg2，需要

pg_config。请添加目录包含pg_config到$ PATH或使用选项：

python setup.py build_ext --pg-config /path/to/pg_config build ...

或在'setup.cfg'中使用pg_config选项。

否则，只需使用以下命令： pip install psycopg2-binary->在消息中也建议使用

如果您不想避免从源代码构建psycopg2，请安装PyPI 改为使用“ psycopg2-binary”软件包。

当我尝试使用pip install psycopg2安装psycopg2时，出现此错误。我该怎么办？
