如何使用 pip 运行 requirements.txt 文件？

Question

I try to run an python project. So I created python virtual environment

sudo python3 -m venv env

After this I activate environment

source env/bin/activate

after this I try to install requirement from requirement.txt file using

pip install -r requirements.txt

but It show an error

ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/var/www/html/selenium/env/lib/python3.8/site-packages/async_generator-1.10.dist-info'

Consider using the --user option or check the permissions.

Don't create the environment with sudo since it will be owned by root. You don't need sudo because you should create the environment in a place you have access to. Preferably somewhere in your user/home directory (depending on OS).
