Python Gunicorn导入错误

我正在尝试让一个烧瓶应用程序与gunicorn一起工作

当我执行以下操作时，它会起作用：

. env/bin/activate
python app.py

然而，当我这样做时：

. env/bin/activate
gunicorn app:app -b localhost:8005

它失败了，原因是导入simplejson存在问题。simplejson安装在virtualenv和std python库中

好吧，玩过之后，是simplejson引起了骚动。删除导入将允许系统运行。然而，simplejson是一个关键元素

从views.py导入：

from kf import app, mail, model, va, pdfgen
from flask import render_template, request, session, redirect, url_for, jsonify, make_response, g, flash, abort
from flask.ext.mail import Message
import simplejson

---

它是否成功导入了任何其他非内置模块？为了帮助调试，请尝试在其上方添加：

import sys

print（sys.path）

@tadhgmdonald Jensen:是的，它导入了flask、flask core和其他模块，将sys.path添加到底部OK，我使用flasks内置json函数短期修复了它，移除simplejson，并将所有simplejson切换到flask.json如何在virtualenv中安装它？你确定它真的安装在那里了吗？您是否使用requirements.txt？

from kf import app, mail, model, va, pdfgen
from flask import render_template, request, session, redirect, url_for, jsonify, make_response, g, flash, abort
from flask.ext.mail import Message
import simplejson
