pipenv不安装软件包

Question

我是Pipenv的新手，我正在为我的个人项目学习它。我无法使用pipenv安装requests模块，我也不知道为什么。

这些是导航到我刚刚克隆的工作目录之后的步骤。我用Homebrew来安装pipenv。

# Load the virtualenv
bash-3.2$ pipenv shell
Shell for UNKNOWN_VIRTUAL_ENVIRONMENT already activated.
No action taken to avoid nested environments.

运行pipenv安装

运行使用requests模块的Python程序。

My@My-MacBook-Pro myproject (master) $ python movie_titles.py --title Spiderman
Traceback (most recent call last):
  File "movie_titles.py", line 5, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

重新安装pipenv请求

My@My-MacBook-Pro myproject (master) $ pipenv install requests
