【问题描述】：

我有一个在 miniconda2 环境中运行的烧瓶服务。我用

安装了 uwsgi 系统范围

sudo pip install uwsgi

现在当我尝试使用 uwsgi 启动我的服务时。

uwsgi --socket 127.0.0.1:5000 --protocol=http --home /home/ankit/miniconda2/envs/venv -w wsgi.py

它给了我以下错误。

标签： python pip uwsgi anaconda conda

【解决方案1】：

试试-w wsgi:<app>，<app> 是 wsgi.py 文件中 Flask 应用程序的名称。

或者使用更明确的

--wsgi-file wsgi.py --callable app
