Python编程：uWSGI配置报错ModuleNotFoundError: No module named 'flask'

flask的uwsig.ini配置文件如下：

[uwsgi]
socket = 127.0.0.1:3031
wsgi-file =  flask_web.py
callable = app
processes = 4
threads = 2
stats = 127.0.0.1:9191

启动

$ uwsgi uwsig.ini

然后报错：

Traceback (most recent call last):
  File "flask_web.py", line 8, in 
    from flask import Flask
ModuleNotFoundError: No module named 'flask'
unable to load app 0 (mountpoint='') (callable not found or import error)

很明显是环境没有指定

[uwsgi]
socket = 127.0.0.1:3031
home = /Users/qmp/.virtualenvs/py3
wsgi-file =  flask_web.py
callable = app
processes = 4
threads = 2
stats = 127.0.0.1:9191

指定环境参数home后再次运行就成功了 也可以指定（四选一即可）：virtualenv、venv、 home、 pyhome

参考：

1. uWSGI - ImportError: No module named os
