当我在Pycharm终端pip install psycopg2中运行时，它给了我这个错误Command "python setup.py egg_info" failed with error code 1 in C:Users...我尝试了很多在stackoverflow上发现的东西，但仍然不起作用。我的pip版本是19.0.3，我的python版本是3.8
在下面的日志中，它还显示Error: pg_config executable not found

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>).
