我正在尝试安装Python模块Scrapy，但找不到requirements.txt文件。我使用的是Python 3.10.4和pip 22.2.2。我试着运行
pip install -r requirements.txt
产生了相同的错误
我在Windows Powershell中键入了以下命令：
pip install scrappy
标准输出：

尝试以下操作：
pip install --ignore-installed scrappy
或者，如果requirements.txt中列出了scrapy(请确保指定了scrappy的版本(，则假设requirements.txt在当前目录中
pip install --ignore-installed -r requirements.txt
