我正在测试谷歌云平台,我在谷歌计算引擎上部署了一个OpenLiteSpeed Django解决方案和一个Ubuntu虚拟机。当它被部署时,一切都像一个符咒一样工作,我能够到达“Hello,world”的起始页面
当我试图通过将/usr/local/lsws/Example/html/demo/app
中的views.py
文件更改为以下内容来添加自己的简单脚本时:
import MySQLdb
from django.shortcuts import render
from django.http import HttpResponse
def getFromDB():
data = []
db = MySQLdb.connect(host="ip",
user="user",
passwd="pw",
db="db")
cur = db.cursor()
cur.execute("SELECT * FROM table")
for student in students:
data.append(student)
return data
def index(request):
return HttpResponse(getFromDB)
并再次访问IP我遇到以下回溯和错误:
Environment:
Request Method: GET
Request URL: http://ip/

import MySQLdb
Exception Type: ModuleNotFoundError at /
Exception Value: No module named 'MySQLdb'
我尝试在/usr/bin
目录中运行./pip3 install mysqlclient
,同时运行sudo apt install python3-dev
和sudo apt install libmysqlclient-dev
但没有成功。有人能帮忙吗?我是一个应用程序新手
更新:
因此,通过尝试一系列不同的东西,我最终通过将cd'ing放入/usr/bin
并执行sudo -H ./pip3 install mysqlclient
来解决问题。我不完全确定为什么它在执行./pip3 install mysqlclient
时没有给我任何权限错误-但是现在问题解决了
是否安装了MySQLdb?当你进入pip3列表时,你看到了吗
我在文档中看到,建议像这样导入MySQLdb
