目标：让Gunicorn服务于烧瓶应用
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。在我用来管理该Web服务器的帐户的主目录中，有一个项目文件夹，因为我正在从工作站上对其进行处理。这是从项目文件夹中运行的树输出：

│ ├── build

我已经在Venv中安装了gunicorn。我还导出了烧瓶教程中所示的环境变量。
我还配置了manifest.ini和setup.py以使该程序可安装。我试图通过在项目文件夹中运行以下命令进行安装：
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
在使用“ flask run”后，我已经验证了应用程序本身是否在我的工作站上运行。
如果您需要任何文件的代码，请告知我以及最佳的共享方式。以下是一些我认为目前相关的代码：
setup.py：
from setuptools import find_packages, setup
setup(
name='flaskr',
version='1.0.0',
packages=find_packages(),
include_package_data=True,
zip_safe=False,
install_requires=[
'flask',
],
)
manifest.in：
include flaskr/schema.sql
graft flaskr/static
graft flaskr/templates
global-exclude *.pyc

我试图通过关注另一篇文章https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-14-04来发现此问题的原因 当我运行此命令时：
gunicorn --bind 0.0.0.0:8000 wsgi

这是wsgi.py：
from [the name of my project folder] import app
if __name__ == "__main__":
app.run()
我怀疑我在wsgi.py中命名错误的内容
答案 0 :(得分：-1)
在尝试导入应用程序实例之前，尝试将项目的路径插入sys.path。
wsgi.py：
import os
import sys
directory = os.path.dirname(os.path.realpath(__file__))
app_directory = os.path.join(directory, 'flaskr')
if directory not in sys.path:
sys.path.insert(0, directory)
if app_directory not in sys.path:
sys.path.insert(0, app_directory)
from flaskr import app
if __name__ == '__main__':
app.run()
