Django多site-packages路径引发ModuleNotFoundError的解决及PyCharm配置

问题详情 #

项目及包文件的正确路径为：

C:\Users\mattk\Box\WeConsent

但运行项目时，系统错误地调用了其他项目虚拟环境的Python解释器：

C:\PythonProjects\VoterSay7\venv\Scripts\python.exe  # 该环境未安装所需依赖包

实际应使用当前项目路径执行运行命令：

C:\Users\mattk\Box\WeConsent\manage.py runserver localhost:8000

终端报错回溯如下：

C:\PythonProjects\VoterSay7\venv\Scripts\python.exe 
C:\Users\mattk\Box\WeConsent\manage.py runserver localhost:8000

PyCharm配置修正步骤 #

• 打开PyCharm并加载WeConsent项目
• 点击顶部菜单栏File → Settings（Windows/Linux）或PyCharm → Settings（Mac）
• 在设置窗口中展开Project: WeConsent → Python Interpreter
• 点击右上角齿轮图标，选择Add
• 在弹出窗口中选择Existing environment，点击右侧文件夹图标，定位到项目对应的Python解释器（若项目有独立虚拟环境，选择项目目录下venv\Scripts\python.exe；若无则选择对应版本的全局Python解释器）
• 确认路径后点击OK，回到Python Interpreter页面，确保已切换为正确的解释器
• 检查运行配置：点击顶部工具栏的运行配置下拉框，选择Edit Configurations
• 在配置窗口中找到Django的runserver配置，确认Python interpreter已选择刚才设置的正确解释器
• 保存配置后重新运行项目
