Django没有名为“ psycopg2”的模块

Question

Hey I tried find something what resolve my problem but nothing helped me. I'm trying to install 'psycopg2' to using PostreSQL in my project.

I tried install it using pip, easy_install ect. I'm using PyCharm so i tried install it i "install package window" but I'm getting something like this:

Collecting psycopg2
  Using cached psycopg2-2.6.1.tar.gz
    Complete output from command python setup.py egg_info:
    running egg_info
    creating pip-egg-info\psycopg2.egg-info
    writing pip-egg-info\psycopg2.egg-info\PKG-INFO
    writing dependency_links to pip-egg-info\psycopg2.egg-info\dependency_links.txt
    writing top-level names to pip-egg-info\psycopg2.egg-info\top_level.txt
    writing manifest file 'pip-egg-info\psycopg2.egg-info\SOURCES.txt'
    warning: manifest_maker: standard file '-c' not found

    Error: pg_config executable not found.

    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'.

    ----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Bartek\AppData\Local\Temp\pycharm-packaging0.tmp\psycopg2\

I'm working on Windows for now, can you give me some advice how resolve this problem? I'm sitting on it more than 2 hours :(

After install clean PostgreSQL i tried again "pip install psycopg2" and i got:

Answer 1

Install Postgresql , add C:\\Program Files (x86)\\PostgreSQL\\9.4\\bin\\ to your path and try pip install psycopg2 again.

Looks like you need to download Visual Studio as well.

Answer 2

I resolve my problem using:

This is only solution for me. Visual, PostgreSQL doesn't help for this.
