Question

更新/解决方案：

在此问题的答案中找到了解决方法/解决方法： Pip installing packages to global site-packages when inside virtual environment。像该问题的OP一样，我也正在运行具有最新更新的Manjaro Linux。

当尝试将带有pip install django-import-export的django import_export模块安装到我的虚拟环境中时，表明已成功安装，但是，当我尝试在项目中使用import_export模块时，收到错误消息：{ {1}}。我也无法列出以前使用ModuleNotFoundError: No module named 'import_export'或pip list安装的应用程序，并且尝试使用pip freeze升级pip版本还表示已成功安装新版本，但未成功安装安装在我的虚拟环境中。

我已确保使用pip install --upgrade pip激活我的虚拟环境。

pip install django-import-export

WARNING: You are using pip version 19.2.2, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Pip版本：

(.env) [travis@spooky issuetracker]$ python -V
Python 3.7.4

.env / bin / pip：

(.env) [travis@spooky issuetracker]$ pip -V
pip 19.2.2 from /home/travis/Documents/Python/Django/Projects/issuetracker/.env/lib/python3.7/site-packages/pip (python 3.7)

我不确定这何时停止工作，因为我以前能够将其他软件包成功安装到同一虚拟环境中。如何确保pip将软件包正确安装到我的虚拟环境中？

更新：

似乎pip安装在.local / lib / python3.7 / site-packages目录中，而不是.env / lib / python3.7 / site-packages。
