配置Pywikibot对接自建MediaWiki实例时的用户名未定义问题排查

在云服务器上搭建了MediaWiki实例，确认Pywikibot的Family配置正常，可通过以下代码获取主页面内容：

# Set up the site
site = pywikibot.Site('en', 'mdswiki')  
# Get the main page
page = pywikibot.Page(site, 'Main Page')
# Print the content of the main page
print(page.text)

操作环境为Jupyter Notebook，但尝试编辑页面时（代码如下）：

new_content = page.text.replace('Foo', 'Bar')
page.put(new_content, summary='Bot: Test edit')

抛出错误：

OtherPageSaveError: Edit to page [[mdswiki:en:Main Page]] failed:
ERROR: username for mdswiki:en is undefined.
If you have a username for that site, please add a line to user config file (user_config.py) as follows:
usernames['mdswiki']['en'] = 'myUsername'

已创建机器人账户并配置BotPassword，得到提示：The new password to log in with Golem@golem is u3g0l89eXXXredcatedXXXdcs3h. Please record this for future reference.

随后在C:\Anaconda3\envs\lamp\Lib\site-packages\pywikibot\scripts\目录下创建了两个配置文件：

• user-config.py

mylang = 'en' 
usernames['mdswiki']['en'] = 'Golem'
password_file = "user-password.py"

• user-password.py

# This is an automatically generated file used to store
# BotPasswords.
#
# As a simpler (but less secure) alternative to OAuth, MediaWiki allows bot
# users to uses BotPasswords to limit the permissions given to a bot.
# When using BotPasswords, each instance gets keys. This combination can only
# access the API, not the normal web interface.
#
# See https://www.mediawiki.org/wiki/Manual:Pywikibot/BotPasswords for more
# information.
('Golem', BotPassword('golem', 'u3g0lXXredactedXXXXXs3h'))

已重启内核重新加载配置，但错误依旧。请问是配置文件位置错误，还是用户名、密码参数配置有误？我尝试过多种Golem名称和BotPassword的写法，仍无法解决。
