Python无法在工作计算机上找到已安装的模块-Windows OS

Posted 2023-02-23

【中文标题】Python无法在工作计算机上找到已安装的模块-Windows OS

【英文标题】：Python unable to find installed modules on work computer -Windows OS

【发布时间】：2022-01-22 11:55:48

【问题描述】：

我有一个我写的 Python 脚本，它在我作为管理员的家里的电脑上运行良好。我试过在工作中使用它（使用网络驱动器，我不是管理员），我一直遇到这个问题，我使用的任何模块都无法识别。

我使用 python -m pip install 安装了每个包。当我从命令提示符运行 python 时，我可以导入和使用每个包；但是，当我尝试使用 VS 代码运行代码时，它返回“ModuleNotFoundError: No module named '_______'。

我手动选择了一个解释器，甚至在 launch.json 文件中为“env”的“PYTHONPATH”属性指定了站点包的绝对路径。我什至还尝试将程序移动到站点包，但仍然找不到包。

如果我需要包含任何其他信息，请告诉我。我已经尽我所能搜索了几个星期的在线资源来寻找类似的问题，但到目前为止我找到的答案都没有奏效。非常感谢任何帮助，因为我真的很想让这个脚本工作。

【参考方案1】：

您似乎没有在 VSCode 中选择正确的 Python 解释器。

虽然您可以在命令提示符下成功执行 python 文件，但您应该已经在全局 python 环境中安装了这些包。但是你在VSCode中没有选择这个python环境。

您可以点击VSCode左下角的python解释器来切换python解释器。

你可以执行pip show packagename获取包的安装位置，pip --version获取你正在使用的pip，print(sys.prefix)获取你正在使用的python环境。
