python - 在 docker 容器上构建图像以运行自己的 Django 应用程序

Question

我正在尝试构建一个图像以在 Docker 容器中运行，并使用自己现有的 Django 应用程序执行以下命令

    sudo docker build -t avilaholding/clubmercado ~/Documents/docker/cmimage

但是我用 psycopg2 得到了这个错误

Collecting pathspec==0.3.4 (from -r /srv/clubmercado/requirements.txt (line 23))
  Downloading pathspec-0.3.4.tar.gz
Collecting psycopg2==2.6.1 (from -r /srv/clubmercado/requirements.txt (line 24))
  Downloading psycopg2-2.6.1.tar.gz (371kB)
    Complete output from command python setup.py egg_info:
    running egg_info

    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'.

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip install -r $DOCKYARD_SRVPROJ/requirements.txt' returned a non-zero code: 1

我认为这可能是因为它在 python 2.7 上运行，但我希望它在 python 3.5 上运行。我在 Ubuntu 16.04 上安装了这两个版本。

此外，当我执行 pip --version 或者 pip3 --version

会提示安装的版本已经是9.0.1版本
