一、错误提示AttributeError: module pkgutil has no attribute ImpImporter准备在PyCharm下面安装pandas报错AttributeError: module pkgutil has no attribute ImpImporter. Did you mean: zipimporter?安装python包反复尝试不同版本的问题。折腾一下后在终端使用以下命令解决py -m ensurepip --upgrade再次安装pandas成功。刚开始运行有点问题好像没装载上。在软件包中再次安装一下成功。调试正常。二、二次波折换了另一台比较复杂的系统又出现类似的错误。在终端使用以下命令重新安装成功。curl https://bootstrap.pypa.io/get-pip.py -o get-pip.pypython get-pip.py​ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python get-pip.py ​解释原因::核心原因虚拟环境里有一套“过旧的 pip / setuptools / pkg_resources”不兼容 Python 3.12。在 Python 3.12 中pkgutil.ImpImporter 已被彻底移除。但你当时使用的 pip 内部仍通过 pkg_resources 去访问这个已删除的 API于是触发了AttributeError: module pkgutil has no attribute ImpImporter也就是解释器是新的3.12包管理工具是旧的 → 直接崩。你刚才为什么用 get-pip.py 就好了get-pip.py 强制下载并重装了最新 pip25.3它自带了适配 Python 3.12 的实现不再使用 ImpImporter。随后又升级了 setuptools 和 wheel三件套版本重新对齐所以错误消失。这一步相当于修复了被破坏/过旧的包管理栈。界面演示(venv) PS C:\Users\stu-\PycharmProjects\pythonProject2 curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py (venv) PS C:\Users\stu-\PycharmProjects\pythonProject2 python get-pip.py Collecting pip Using cached pip-26.1.1-py3-none-any.whl.metadata (4.6 kB) Using cached pip-26.1.1-py3-none-any.whl (1.8 MB) Installing collected packages: pip Attempting uninstall: pip Found existing installation: pip 26.1.1 Uninstalling pip-26.1.1: Successfully uninstalled pip-26.1.1 Successfully installed pip-26.1.1三、部分提示信息Windows PowerShell版权所有 (C) Microsoft Corporation。保留所有权利。尝试新的跨平台 PowerShell https://aka.ms/pscore6[PyCharm] Your PSReadLine module version (2.0.0) is outdated, which may cause the problem with black lines across the terminal screen:https://learn.microsoft.com/windows/terminal/troubleshooting#black-lines-in-powershell-51-6x-70Install the latest version by running: Install-Module PSReadLine -MinimumVersion 2.0.3 -Scope CurrentUser -ForceAfter the installation, open a new terminal tab.(venv) PS C:\Users\stu-\PycharmProjects\pythonProject pip install pandasERROR: Exception:Traceback (most recent call last):File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\cli\base_command.py, line 160, in exc_logging_wrapperstatus run_func(*args)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\cli\req_command.py, line 247, in wrapperreturn func(self, options, args)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\commands\install.py, line 326, in runsession self.get_default_session(options)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\cli\req_command.py, line 98, in get_default_sessionself._session self.enter_context(self._build_session(options))~~~~~~~~~~~~~~~~~~~^^^^^^^^^File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\cli\req_command.py, line 125, in _build_sessionsession PipSession(cacheos.path.join(cache_dir, http) if cache_dir else None,...3 lines...ssl_contextssl_context,)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\network\session.py, line 343, in __init__self.headers[User-Agent] user_agent()~~~~~~~~~~^^File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\network\session.py, line 175, in user_agentsetuptools_dist get_default_environment().get_distribution(setuptools)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\importlib\_envs.py, line 188, in get_distributionreturn next(matches, None)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\importlib\_envs.py, line 185, in genexprfor distribution in self.iter_all_distributions()~~~~~~~~~~~~~~~~~~~~~~~~~~~^^File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\base.py, line 612, in iter_all_distributionsfor dist in self._iter_distributions():~~~~~~~~~~~~~~~~~~~~~~~~^^File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\importlib\_envs.py, line 176, in _iter_distributionsfor dist in finder.find_eggs(location):~~~~~~~~~~~~~~~~^^^^^^^^^^File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\importlib\_envs.py, line 146, in find_eggsyield from self._find_eggs_in_zip(location)File C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_internal\metadata\importlib\_envs.py, line 123, in _find_eggs_in_zipfrom pip._vendor.pkg_resources import find_eggs_in_zipFile C:\Users\stu-\PycharmProjects\pythonProject\venv\Lib\site-packages\pip\_vendor\pkg_resources\__init__.py, line 2164, in moduleregister_finder(pkgutil.ImpImporter, find_on_path)^^^^^^^^^^^^^^^^^^^AttributeError: module pkgutil has no attribute ImpImporter.
