Django / PyCahrm使用/ venv将项目重定位到另一台PC上，找不到`dotenv`模块，无法安装它

编程问答 2022-08-11

问题描述

我将带有/ venv的Django项目（mysite）移至另一台计算机。 在第一台计算机上，它运行良好。哪里有“ dotenv”模块。

在PyCharm中，我将项目解释器设置为： Python 3.7（mysite）C：\ Users \ User \ mysite \ venv \ Scripts \ python.exe

但是新计算机中的“ python manage.py runserver”出现了：

ModuleNotFoundError: No module named 'dotenv'

但是在../mysite/venv/脚本存在文件dotenv.exe中。 还有sobfolder ../venv/lib/site-packages/dotenv/。 在“ PyCharm-Settings-Project解释器”的“程序包”列表中，存在python-dotenv 0.14.0

好的。我尝试通过pip安装dotenv，但是会引发错误： C：\ Users \ User \ mysite \ mysite> pip install dotenv

    The above exception was the direct cause of the following exception:

    ----------------------------------------
Command "python setup.py egg_info" Failed with error code 1 in C:\Temp\pip-install-07by3weo\dotenv\

我尝试这样：pip install --upgrade setuptools，但没有帮助

如何解决？

解决方法

pip安装python-dotenv （不是'dotenv'）。它有效
