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 <module> 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
