Python：'ModuleNotFoundError‘

Question

我试图使用python连接到使用MariaDB的数据库，我在MariaDB网页上使用了脚本，但是导入MariaDB模块时出错。如果我尝试手动导入它，就会得到相同的错误消息。这是一个脚本：

# Module Imports
import mariadb
import sys

# Connect to MariaDB Platform
try:
    conn = mariadb.connect(
        user="root",
        password="password",
        host="10.0.0.2",
        port=65500,
        database="main_db"

    )
except mariadb.Error as e:
    print(f"Error connecting to MariaDB Platform: {e}")
    sys.exit(1)

# Get Cursor
cur = conn.cursor()

这是错误消息：

Traceback (most recent call last):
  File "c:\path\to\myenv\scripts\connectdb.py", line 2, in <module>
    import mariadb
ModuleNotFoundError: No module named 'mariadb'

在此之前，我检查了是否正确安装了mariadb：

C:\Users\user>pip install mariadb
Requirement already satisfied: mariadb in c:\users\user\appdata\local\packages\pythonsoftwarefoundation.python.3.10_qbz5n2kfra8p0\localcache\local-packages\python310\site-packages (1.0.11)
WARNING: There was an error checking the latest version of pip.

C:\Users\user>pip3 install mariadb
Requirement already satisfied: mariadb in c:\users\user\appdata\local\packages\pythonsoftwarefoundation.python.3.10_qbz5n2kfra8p0\localcache\local-packages\python310\site-packages (1.0.11)
WARNING: There was an error checking the latest version of pip.

还试图将mariadb文件夹从自动安装的位置移到我的"connectdb.py“文件所在的文件夹中，但结果相同，但又出现了一个错误：

Traceback (most recent call last):
  File "c:\users\user\documents\pyth\last_connect.py", line 2, in <module>
    import mariadb
  File "c:\users\user\documents\pyth\mariadb\__init__.py", line 10, in <module>
    from ._mariadb import (
ModuleNotFoundError: No module named 'mariadb._mariadb'

您可能安装了两个不同的python解释器。检查是否在代码编辑器中选择了正确的。
