python、django、wsgi应用程序不工作

    问题

    我们想使用wsgi运行taiga.io,但在尝试了1小时后,我们需要其他人的帮助。我们不理解跟踪,但我们认为现在运行正确的wsgi二进制文件: 

    gunicorn taiga.wsgi

    但是

    1. webservice仍然不会启动并返回无用的跟踪。
    2. 我们已经在谷歌上搜索了它,并尝试了各种各样的黑客攻击,但似乎没有一个有用的。
    3. 我们试图设置django_settings_模块,但不确定是否需要
    4. 我们甚至不知道django是否调用了正确的wsgi二进制文件

    为什么工人不能开机?是否有更详细的调试工作人员在某处?

    版本

    • Taiga-背面-3.3.13
    • 蟒蛇3.6-django-1.11.13
    • Python 3.65
    • 古尼孔-19.7.1
    • NixOS版本18.03.d6c6c7f-nixcloud_598d0c5(impala)

    任务:通过wsgi运行taiga

    我在整合 https://github.com/betaboon/nixpkgs/blob/445563d6575d7e8cb21768570b837ea3d816dee8/nixos/modules/services/web-apps/taiga.nix 目前,在NixCloud Webservices中,当它工作正常时: 

    ${taiga-back}/bin/manage.py runserver --nostatic "127.0.0.1:8000"

    我们与wsgi有问题: 

    systemd.services.taiga-back = rec {
 description = "${config.uniqueName} main service (taigaio)";

  wantedBy      = [ "multi-user.target" ];
  after         = [ "network.target" ];

  environment = let
    python = pkgs.python3;
    penv = python.buildEnv.override {
      extraLibs = [
        taiga-back
        pkgs.python3Packages.gunicorn
        pkgs.python3Packages.gevent
        pkgs.python3Packages.celery
        pkgs.python3Packages.django
      ];
    };
  in {
    PYTHONPATH = "${taigaBackConfigPkg}:${penv}/${python.sitePackages}/:${taiga-back}/lib/python3.6/site-packages";
    DJANGO_SETTINGS_MODULE = "settings";
  };
  serviceConfig = {
    User = "taigaio-t1";  # FIXME hardcoded
    Group = "taigaio-t1"; # FIXME hardcoded
    WorkingDirectory = "${config.stateDir}/www";
    PrivateTmp = false;
    # FIXME: hardcoded taigaio-t1 user/group
    # FIXME: port 8000 is hardcoded
    ExecStart =

${pkgs.python3Packages.gunicorn}/bin/gunicorn taiga.wsgi \
        -k gevent \
        -u taigaio-t1 \
        -g taigaio-t1 \

    好吧,经过几天的努力终于找到了解决问题的办法:

    下面的代码用于描述environment.pythonpath(稍后用于wsgi(gunicorn)服务),它不包含taiga back python库。 

      python = pkgs.python3;
  penv = with pkgs.python3Packages; with myPythonPackages;  python.buildEnv.override {
    extraLibs = [
      taiga-back
      pkgs.python3Packages.gunicorn
