Python 发布正在运行的gunicorn以服务flask应用程序

目标：让gunicorn提供烧瓶应用程序

尝试：运行以下命令：

gunicorn [the name of my project folder]:flaskr

输出：

我已将此项目部署到我的web服务器。在我用来管理此Web服务器的帐户的主目录中，我有一个项目文件夹，因为我在工作站上处理它。以下是从项目文件夹中运行的树输出：

├── flaskr
│   ├── auth.py
│   ├── build
│   ├── db.py
│   ├── db.pyc
│   ├── dist
│   ├── flaskr.egg-info
│   ├── __init__.py

│   ├── pyvenv.cfg
│   └── share
└── venv.sh

pip install -e

我已经在venv中安装了gunicorn。我还导出了环境变量，如flask教程中所示

我还配置了manifest.ini和setup.py以使程序可安装。我已尝试从项目文件夹中运行以下程序进行安装：

├── flaskr
│   ├── auth.py
│   ├── build
│   ├── db.py
│   ├── db.pyc
│   ├── dist
│   ├── flaskr.egg-info

│   ├── pyvenv.cfg
│   └── share
└── venv.sh

pip install -e

我得到以下输出：

Usage:   
  pip install [options] <requirement specifier> [package-index-options] ...
  pip install [options] -r <requirements file> [package-index-options] ...
  pip install [options] [-e] <vcs project url> ...
  pip install [options] [-e] <local project path> ...
  pip install [options] <archive url/path> ...

-e option requires an argument

清单1.in：

include flaskr/schema.sql
graft flaskr/static
graft flaskr/templates
global-exclude *.pyc

我试图通过另一篇文章来发现这个问题的原因， 运行此命令时：

gunicorn --bind 0.0.0.0:8000 wsgi

我怀疑我在wsgi.py中命名了错误的东西，请尝试在尝试导入应用程序实例之前将项目的路径插入sys.path

wsgi.py：

导入操作系统 导入系统 directory=os.path.dirnameos.path.realpath\u文件__ app_directory=os.path.joindirectory，“flaskr” 如果目录不在sys.path中： sys.path.insert0，目录 如果app_目录不在sys.path中： sys.path.insert0，应用程序目录 从flaskr导入应用程序 如果uuuu name uuuuuu='\uuuuuuu main\uuuuuuu'： app.run

请参阅显示我仍在努力解决此问题的编辑。无论是谁投票否决了此答案，请在我实施此解决方案之前解释为什么会这样做？
