我正在尝试安装项目的所有要求，所以我运行命令

pip install -r requirements.txt

但它给出了错误

Downloading/unpacking psycopg2==2.6 (from -r requirements.txt (line 58))
  Downloading psycopg2-2.6.tar.gz (367kB): 367kB downloaded
  Running setup.py (path:/tmp/pip_build_root/psycopg2/setup.py) egg_info for package psycopg2

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/psycopg2

现在我知道我必须安装 postgresql-server 所以我使用了以下命令

sudo apt-get install postgresql

到目前为止一切都很好，然后我跑了

sudo apt-get install python-psycopg2

然后我运行我的命令再次安装要求但得到了同样的错误然后我在谷歌上搜索并尝试了

sudo apt-get install libpq-dev

但我收到以下错误

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libpq-dev : Depends: krb5-multidev but it is not going to be installed
             Depends: comerr-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

现在我无法检测和纠正损坏的包裹......请帮助我......
