如何在Mac命令行中返回python虚拟环境

Question

I am having a bit of difficulty reinitiating my virtual environment on my preprod server on command line. I think when I quit out of my preprod server the other day, I also quit out of my virtual environment, because now it doesn't say (env) in front of the preprod prompt:

Before: (env) SAS@preprod:~$
Now: SAS@preprod:~$

I am logged into my preprod server now, and I have a virtual_environment_command.txt file, and a config file accessible. I just don't know how to activate either of those documents so I can utilize my virtual environment for testing the code for an api document I'm working on. Thanks!

Answer 1

You have to find the directory where the virtualenv was created. eg when you created it using virtualenv env it would create a directory called env and you can activate it using:

source env/bin/activate

Answer 2

Thank you so much for your responses! They were very helpful! I also ended up clicking the up arrow enough times to figure out what I typed in before to reactivate the venv a few days ago (yes it was a lot of clicking, lol) and found that the following command also proved to fix the problem:

SAS@preprod:~$$(cat virtual_environment_command.txt )

And that extra $ is not a typo, it goes the prompt and then $(cat virtual_environment_command.txt)

Thank you again!
