【问题描述】：
我有一个 requirements.txt 文件，其中包含我的 Flask 应用程序所需的 python 包的所有信息。这是我所做的：
python3 -m venv venvsource venv/bin/activatesudo pip install -r requirements.txt
当我尝试使用pip list 检查软件包是否安装在虚拟环境中时，我没有看到这些软件包。谁能告诉我出了什么问题？

您没有从 venv 运行 pip，因为您使用的是
sudo，请在不使用 sudo 的情况下运行 pip -
@IainShelvington 但是，当我尝试在没有 sudo 的情况下运行 pip 安装时，出现以下错误：
ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/var/www/html/flaskapp/venv/lib/python3.8/site-packages/certifi-2021.5.30.dist-info' Consider using the--user` 选项或检查权限。 `
