【问题描述】：
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。部署后，一切都像一个魅力，我能够到达“你好，世界”起始页面。
当我尝试通过将views.py 中的views.py 文件更改为：
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)
再次访问 IP 我遇到了以下回溯和错误：
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，以及sudo apt install python3-dev 和sudo apt install libmysqlclient-dev，但没有成功。有人能帮忙吗？我是使用应用程序的新手。
更新：
所以，通过尝试一堆不同的东西，我最终通过 cd'ing 进入/usr/bin 并执行sudo -H ./pip3 install mysqlclient 解决了这个问题。我不完全确定为什么在执行 ./pip3 install mysqlclient 时它没有给我任何权限错误 - 但是现在问题已经解决了。
【问题讨论】：
-
看这里stackoverflow.com/questions/47490797/…你应该切换到另一个驱动程序，因为这不再受支持
-
@nbk 当我在虚拟机中直接通过 SSH 运行 python3 时，我可以
import MySQLdb没有问题。 -
我使用 import mysql.connector 没有问题，你的 umport 不适用于我和其他人
-
@nbk 这很奇怪...我会尝试切换连接器。
-
通过运行
sudo -H ./pip3 install mysqlclient而不是./pip3 install mysqlclient修复了错误
