`ModuleNotFoundError: No module named 'psutil'` when import psutil module

Question

In my flask project, I use uwsgi run it.

in my project there has import psutil .

off course I installed latest psutil in my venv:

(venv) [root@7338cdd80407 ssl-node]# pip3 install --upgrade psutil
Requirement already satisfied: psutil in /www/wwwroot/ssl-node/venv/lib64/python3.6/site-packages (5.8.0)

but when I execute my flask code, there get error ModuleNotFoundError: No module named 'psutil' :

EDIT-01

my pip3 and pip both comes from venv :

(venv) [root@7338cdd80407 ssl-node]# which pip3
/www/wwwroot/ssl-node/venv/bin/pip3
(venv) [root@7338cdd80407 ssl-node]# which pip 
/www/wwwroot/ssl-node/venv/bin/pip

EDIT-02

My python3 path:

(venv) [root@7338cdd80407 ssl-node]# which python3
/www/wwwroot/ssl-node/venv/bin/python3

I use uwsgi -d --ini uwsgi_prod.ini execute my flask project:

uwsgi_prod.ini content:

[uwsgi]
http=0.0.0.0:5000
processes=4
threads=2
master=true
pythonpath=/www/wwwroot/ssl-node/ssl-node
module=manager
callable=app
memory-report=true
buffer-size=32768
static-map=/static=/www/wwwroot/ssl-node/ssl-node/static
daemonize=/www/wwwroot/ssl-node/ssl-node/log/uwsgi.log

you see there execute from manager.py : the content of it:

#-*- coding:utf-8 -*-
# Author: jack

import sys,os

path = os.path.join(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
sys.path.append(path)

from api import app

if __name__ == "__main__":
    app.run("0.0.0.0")

Your problem is that uwsgi is not being run from inside the vent. To do so run the application with:

uwsgi -d --ini uwsgi_prod.ini -H /www/wwwroot/ssl-node/venv/bin/python3
