我正在尝试遵循有关 pipenv 和 virtualenv 的指南：http ://docs.python-guide.org/en/latest/dev/virtualenvs/ 。问题是，我在尝试时遇到了问题$ pipenv install requests（在我的情况下我认为应该是$python3 -m pipenv install requests因为只是pipenv返回未找到的命令。）
为什么权限被拒绝？
我是一个终端菜鸟，所以请耐心等待。
$ pip3 install --user pipenv
$ python3 -m pipenv
Usage: __main__.py [OPTIONS] COMMAND [ARGS]...
$ python3 -m pipenv install requests
