问题描述

gunicorn 启动python项目时，抛异常：ModuleNotFoundError: No module named 'gunicorn.app'; 'gunicorn' is not a package
具体异常如下：

Traceback (most recent call last):
  File "/home/dev/anaconda3/envs/torch/bin/gunicorn", line 5, in <module>
    from gunicorn.app.wsgiapp import run
ModuleNotFoundError: No module named 'gunicorn.app'; 'gunicorn' is not a package

问题分析

项目启动时，找不到gunicorn.app安装包 vi gunicorn，先查看下安装包的查找路径，添加了print输出

查看输出sys.path发现项目依赖环境在项目的后面，找不到依赖包也是正常

解决办法

查看抛异常语句中，找到报错的文件，按报错的文件位置cd进去，vi命令打开报错文件，把依赖环境路径添加到要导包报错的前面，问题得以解决！这个配置路径要根据自己环境安装的实际路径来配置 sys.path[0]='/home/dev/anaconda3/envs/torch/lib/python3.6/site-packages'
