pip install -r requirements.txt 不安装任何东西

Question

我像这样创建我的requirements.txt

delorean==1.0.0
requests==2.18.4

我尝试在虚拟环境中调用 pip install -r requirements.txt。但它没有显示任何东西。

gangzhao@Gangs-MacBook-Pro yashirq % source .venv/bin/activate
(.venv) gangzhao@Gangs-MacBook-Pro yashirq % pip install -r Practice/Python/Automation/requirements.txt
(.venv) gangzhao@Gangs-MacBook-Pro yashirq % python
Python 3.8.2 (default, Nov  4 2020, 21:23:28)

Type "help", "copyright", "credits" or "license" for more information.
>>> import delorean
Traceback (most recent call last):

ModuleNotFoundError: No module named 'delorean'
