在GCP部署OpenLiteSpeed django解决方案时，“ModuleNotFoundError（“No module named 'MySQLdb'”）”错误。

我正在测试Google Cloud Platform，我在Google Compute Engine上部署了一个使用Ubuntu虚拟机的OpenLiteSpeed Django解决方案。当部署完成后，一切都运行得很顺利，我可以访问到“Hello, world”的起始页面。

当我尝试通过修改/usr/local/lsws/Example/html/demo/app中的views.py文件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)

并且再次访问IP时，我遇到了以下的追踪和错误信息：

我尝试在/usr/bin目录下运行./pip3 install mysqlclient，以及运行sudo apt install python3-dev和sudo apt install libmysqlclient-dev，但都没有成功。有人能帮忙吗？我在处理应用程序方面还是新手。

更新：

所以，通过尝试了各种不同的方法，我最终通过进入/usr/bin目录并执行sudo -H ./pip3 install mysqlclient来解决了这个问题。我不太确定为什么执行./pip3 install mysqlclient时没有给我任何权限错误，但现在问题已经解决了。
